Bonjour,

Je recherche un moyen de placer une image 
d'arrière plan lors d'une visioconférence
afin de simplement neutraliser

Quelles sont les solutions qui pourraient
convenir sous Linux ?

Merci pour votre aimable attention

Bien à vous

Hi Rodolfo,

As didier gaumet writes, 3canali.wav is not one of
ecasound's supported formats. You should find out what it
is. Maybe try 

file 3canali.wav

Also, ecasound can use libsndfile to expand the range of 
compatible audiofiles for reading and writing.

ecasound -i:libsndfile,audiofile -o alsa

If the extension doesn't match the file format, you can
specify the file type, e.g.

ecasound -i:libsndfile,audiofile,aiff -o alsa

cheers

I'd want to use some other tool - "sox" perhaps - to verify that the file
really does contain three channels of audio.  Can, say, the three channels
be selected one at a time and played back without using the Behringer
box?

I'd also need to be convinced that the alsa part of the command that 
someone posted did actually access the correct channels and try to 
send them somewhere.

I'd probably want to try to use something else - maybe "sox" - to send 
test tones to three named places (as far as alsa is concerned) on the PC
before trying to find out which of those arrived properly at the audio
interface.

I'm not sure that's true; look at 
https://d1aeri3ty3izns.cloudfront.net/media/25/259085/download_259085.pdf
(which is the second pdf linked to from
https://www.gear4music.com/Recording-and-Computers/Behringer-U-PHORIA-UMC404HD-Audio-Interface/1WMY?gclid=EAIaIQobChMIheDYlJKf8AIVgQWiAx0ldgK6EAAYASAAEgI13fD_BwE
 )

which clearly states that the box can stream 4 inputs / 4 outputs.


The PDF you linked to is one of those very annoying manuals that describe
many different units, and it's very hard to understand what any single unit
can do.  Worse, there's no schematic showing where signals can flow to &
from.

I also looked at an Amazon listing for the box, but it had the same 
problem - people's comments applied to various different models.

Although it does seem to support 4 separate outputs, these might be 
just copies of the signals supplied on the 4 mic/line inputs (so if one was
using this box to record a couple of singers and guitarists - ie 4 inputs
in all - copies of those signals could be played back to the performers).

On the other hand there's a MIX control which appears to change how 
signals coming from the 4 inputs are mixed with those (from a PC?) that
are being played back.  Maybe if that's turned all the way to the PB 
position audio channels from the PC would be directed to the playback
outputs?

I think that's true of the "MAIN OUTPUT" but I'm not sure it also 
applies to the "PLAYBACK OUTPUTS".

This unit has no pan controls, so panning the 4 inputs to positions on a 
stereo image must be something done by mixing software on a PC. 
That makes the buttons that refer to stereo/mono more confusing, as
the box itself has no concept of stereo. 

Does it follow that the box sends 4 inputs to a PC, and the PC might 
send back either/both copies of those 4 inputs and a mixed stereo
image?

Unfortunately I gave up on Gnome and it's family of gnomes many years ago.
But I recall this odd behavior from the past when I was checking the
progress of the Gnome desktop from time to time.

example from 2010
https://forums.opensuse.org/showthread.php/461414-Cannot-Use-Evolution-because-of-Keyring-Password-in-gnome

Even if they come up with OnlineAccounts or whatever - honestly I do not
want to insult anybody, but why the waste of human time?

On the other hand to make the reader laugh I think it is probably good that
these developers are busy with breaking and repairing Gnome all the time,
so that they can not break anything else around :D

If you want a stable desktop you know there is one called Trinity Desktop
(TDE) - it just works. But upfront the Evolution monster will behave the
same if you insist using it :D

Evolution uses GNOME Online Accounts. Check that no error is reported in the 
"Online Accounts" category under "Settings" (assuming the GNOME desktop).

"Umm, well" is hardly an adequate reponse to Andrei POPESCU's

you will be waiting a long time.

Hi Rodolfo,

Ecasound is pretty convenient for routing audio.

If you connect three powered speakers to the first three
channels of a (sufficiently capable) soundcard and you're
using ALSA (the default low-level linux audio API), it's
pretty simple:

For example,

ecasound -i:3ch.wav -f:16,3,44100 -o:alsa,default



Four years ago this interesting thread.  Now I've purchased a Behringer
UMC404HD 4-channels audio interface and finally want to do my experiment.  Now
I have a 3-channel .wav file and 3 loudspeakers connected to Behringer's

One more thing: on the back of Behringer there are two groups of `playback
outputs': group A and group B.  Each of the two groups has 4 holes: 2 black
6.35mm, one red RCA and one white RCA.  Please help also to understand how to
use them for my special purpose.  Besides, on Behringer's back there is one
more group of outputs called `Main Out' and including two 6.35mm and two XLR.

Thanks in advance for any help,

Hello Rodolfo,

I might be wrong (I don't mix nor record) but I think there are two 
distinct problems:


a) the wav file you generated is not supported by ecasound because its 
type (codec) is neither (L)PCM nor IEEE_FLOAT

https://en.wikipedia.org/wiki/WAV
So, either you produce a wav file encoded in LPCM to use ecasound, or 
you use another tool than ecasound that supports the codec you used to 
produce your wav file


b) https://mediadl.musictribe.com/media/sys_master/h7e/hfb/8849567252510.pdf
your audio interface is a stereo one: it has only two channels (Left 
+Right) as outputs.  Even if there are 3 groups of output, they all play 
the same thing, a stereo signal. Basically, I imagine that a typical 
situation would be to have a mixer or a Public Address (PA) system on 
MAIN, and 2 different paris of active monitors on A and B.
If you want a 3 channels output, you need tou use a multichannel 
hardware, or tinker with 2 stereo interfaces


As a sidenote: are we speaking of the same thing? Inputs are called 
tracks. You could for example have 4 mono tracks for a rock band 
(1:singer, 2:guitar, 3:bass, 4:drums) and each of these tracks are mixed 
and panned to 2 outputs (Left and right) that are called channels.

Je suis l'heureux possesseur d'un Lenovo W520 et j'ai été confronté au même

tombe en panne je dois mettre l'ordinateur à la poubelle.

If someone else can repost it under some of the installation

One more thing: on the back of Behringer there are two groups of `playback
outputs': group A and group B.  Each of the two groups has 4 holes: 2 black
6.35mm, one red RCA and one white RCA.  Please help also to understand how to
use them for my special purpose.  Besides, on Behringer's back there is one
more group of outputs called `Main Out' and including two 6.35mm and two XLR.

Thanks in advance for any help,

Thanks, I could consider doing so in order to organize better
the tutorial displayed at the archive.  I will see what other options
do I have.

A civilised mail user agent will show MIME part boundaries in
a suitable way. I think you don't need to worry too much about
uncivilised MUAs. It's people's choice, after all :-)

Well, I intentionally wrote the script with Unix-style LF line endings.
I don't know if "ash" from Busybox will complain or do something
weird if it finds CR LF line endings instead.  I just wanted to avoid
troubles.

On the other hand, as Mr. Davidson said, it is not very clear
where do one file starts and where do it ends.  In the tutorial,
I refer to them as attached files; but people reading the tutorial
through the archive won't see any "attached file".  If I knew this would
happen, I would rather have put some ---HEADERS--- and
---FOOTERS--- to the files.  It is good to know that they were
correctly sent through email.

Re: KVM: GPU passthrough

error:

Please ensure all devices within the iommu_group are bound to their
vfio bus driver.


This is a known issue with PCIe passthrough: depending on your
mainboard and CPU, some PCIe devices will be grouped together,
and you will either be able to forward _all_ devices in the
group to the VM or none at all.

(If you have a "server" GPU that supports SR-IOV you'd have
additional options, but that doesn't appear to be the case.)

This will highly depend on the PCIe slot the card is in, as well
as potentially some BIOS/UEFI settings on PCIe lane distribution.

First let's find out what devices are in the same IOMMU group.
From your kernel log:

[0.592011] pci :00:01.0: Adding to iommu group 1
[0.594091] pci :01:00.0: Adding to iommu group 1
[0.594096] pci :01:00.1: Adding to iommu group 1

Could you check with "lspci" what these devices are in your case?

If you are comfortable forwarding the other two devices into the
VM as well, just add that to the list of passthrough devices,
then this should work.

If you need the other two devices on the host, then you need to
either put the GPU into a different PCIe slot, put the other
devices into a different PCIe slot, or find some BIOS/UEFI setting
for PCIe lane management that separates the devices in question
into different IOMMU groups implicitly. (BIOS/UEFI settings will
typically not mention IOMMU groups at all, so look for "lane
management" or "lane distribution" or something along those
lines. You might need to drop some PCIe lanes from other devices
and give them directly to the GPU you want to pass through in
order for this to work, or vice-versa, depending on the specific
situation.)

Note: the GUI tool "lstopo" from the package "hwloc" is _very_
useful to identify how the PCIe devices are organized in your
system and may give you a clue as to why your system is grouped
together in the way it is.

Hope that helps.

Christian

You might attach the shell script as application/x-sh rather
than text/x-sh¹. That should encode it, and display it as an
attachment on the web, as with:

https://lists.debian.org/debian-user/2021/03/msg01494.html

making it easier to download. And mutt, for example, would
display it via the attachment menu, ready for downloading.

AIUI, the policy is to immediately display text/… attachments,
though mutt demarcates them better than firefox does. I suppose
one could always wrap the text file into a trivial shell script.
However, before doing this as a general policy, it's worth
checking that websites you expect to be archiving/forwarding
your posts are not stripping attachments. (Some do.)

¹ I have no idea how different MUAs, and posting sites like
  gmail, would force this. Mutt does it as a matter of course,
  and that can be checked before sending, by first postponing
  the message, and then searching the contents of the Postponed
  mailbox for "Content-Type: application/x-sh".

Cheers,
David.

Je n'en ai pas. Ce n'est pas que je n'aurais pas voulu, j'avais même
acheté une carte-mère supportée par Coreboot il y a une bonne dizaine

Mais je me suis contenté d'une lecture en diagonale de la documentation
de coreboot. Une fois la carte-mère achetée, j'ai découvert que, je ne

que je devais dessouder un composant, le flasher, puis le ressouder.
Cette perspective a fait voler en éclat mes velléités d'émancipation. Je

How it works is just perfect - you do not have to care about it.

I don't know of any way to get the debian-user list's web archive to

In the past on this list, I have occassionally sent the content of

Issue with lightdm

[Hans]

Hi folks, 

I am a little stuck with an issue with light dm.




The problem:
When I am starting lightdm and then starting LXDE, I get a popup-window telling 
"Exhausted all available authentication mechanisms (tried: EXTERNAL) (available 
EXTERNAL)"

(Mine is in German, as I am using a German environment, but that does not 
matter.)

When I cllick the message away, then LXDE is started, but several plugins in 
the taskbar 
are not running. 

However, when logging out of LXDE and restarting LXDE again, then everything is 
working normal. 




Investigations:

In /var/log/user.log I can see the same messages (many!) as above described:

Apr 22 19:49:23 localhost lightdm[7160]: Failed to get system bus: Exhausted 
all 
available authentication mechanisms (tried: EXTERNAL) (available EXTERNAL)

I searched the web for a solution, and I believe, it is just a timing problem, 
with the dbus 
system. IMO some thing is inhibiting the syncronisation of the dbus system. 

I tried to deinstall nscd (had the hope, the system will become faster) , but 
then lightdm 
is not starting any more. 

Also tried, to deinstall nscd and then to change from lightdm to sddm, kdm and 
gdm. 
That let kdm, sddm or gddm start, but it let me not start LXDE.

So I reinstalled nscd again.




Questions: 

I saw in te internet, that this behaviour is well known, but not in Debian, 
mostly Ubuntu 
(older versions) and RedHat.

Some told, the solution might be a forced delay, but this makes the starting 
more slow 
tnan wanted.

Do you have any idea, how to fix this? Is this a bug and shoulsd be filed?

Thanks for reading this and all your help!

Best regards

Hans

 b) an exposed "inet" user for the session should be defined with a
RAM drive as its home directory;
 c) for whom -exclusively- the network card's device driver should be
installed (is here a hack to install a device driver entirely from
user space? probably, a Debian HURD kind of thing on which the basic
hook for the networking service is exposed and a user space program
would take it from there?);
 d) then all access to the Internet go through a client proxy run by "inet";
 e) acting as a squid-like application proxy;
 e.1) parsing all text/html content coming in, first cleansing it into
well-fomed xhtml with some HTML parser, then using XPath, java
Nasshorn, the principles of the Burp Suite + wireshark + page Reader +
...;
 e.1.1) sanitzing the page into alpha-offset format;
 e.1.2) not the received, but a sanitzed, topical, content centric
page with all the distracting "attentional" nonsense removed will be
displayed to the user (page reader on steroids);
 e.1.3) it maintain a local cache of the accessed data (videos, pdf
files, ...) and adjusts all links on the flight to the local paths
(storage space is very cheap, anyway);
 e.1.4) using XPaths of the sanitized page, you would be able to
exactly authorize the java script that you want to let through and
blanket "yeah, sure!" the rest of it, including those bsing "we care
about your privacy" (isn't that the very definition of not having
privacy that other people "care" about it?), "user agreements"
authorization of cookies, right on the proxy ebfore it reaches your
field of view/consciousness with the option of sending bogus
information actively, passively or by request, per site, section of
the page ...;
 e.1.5) cookies, user agent, ... will be managed by the proxy, so
little as possible will be exposed;
 f) based on the request headers the proxy would create a new
folder/jail each time a new domain is accessed (probably even the
option to run macchanger?);
 g) based on the critical XPaths a "processing signature" will be kept
for pages, domains, URL paths frequented;
 h) inet had no access to the PATH or any other local variables or
files, it would only know of its own jail;
 i) many/most/all? applications assume/demand Internet access. All
such access attempts should be logged with traceable information so
that you can inspect what it is "that application was attempting to do
which it shouldn't be doing" (tm);
 j) while shutting down "inet" will permanently save the cookies and
such which matter, the rest will be physically "hasta la vista,
babied" since it was kept in RAM anyway;
 k) that proxy could be used as password jar and could as well work as
agent regularly checking if you've got new or certain kinds of email
...

 These is nothing really "new" in that spec. All the pieces either
exist or their functional requirements can be achieved with
configuration changes. It is assembling of all pieces which matters
and may be problematic.

 Do you know of such previous "paranoid" art?

 Any Linux/debian friendly network firmware you would recommend to
make that project easier?

 Any ideas come to mind? Any hints or death threats you would share?

Bonjour,

Sur le Thinkpad, c'est sans doute intéressant. Mais attention aux
autres modèles, les bios/efi et autres joyeusetés sont parfois buggués
sur ces modèles et empêchent un bon fonctionnement sous autre chose que
Windows. J'ai acheté des non Thinkpad à deux disques durs pour ma boîte,
sous Windows le lecteur de CD et les deux disques étaient reconnus, sous
un autre système, c'était au choix le second disque ou le lecteur de CD.
J'admets que parfois, on peut avoir de la chance dans l'autre sens. Un
Lenovo Thinkpad Edge livré avec Windows7 (64 bits) refusait de
reconnaître plus de 4 Go de mémoire alors que la même machine avec la
même mémoire tourne parfaitement avec un Linux ou un NetBSD et 8Go de
mémoire mais a des problèmes de réveil après mise en veille (bug EFI)...

Bien cordialement,

JKB

Il n'y a pas méchanceté à dire ça :-)

Mes reboot sur la sauvegarde (sda2) et sda1 ont toujours parfaitement 
fonctionné.  C'est depuis peu et inexplicable.

rsync fait le clonage de sda1 vers sda2.
Le fichier "/etc/fstab" de sda2 contient bien l'UUID de la partition sda2,
et pareil pour sda1.

e2fsck, avant dernier noyau, mise à jour apt, /var/log/syslog = OK.

Je tape en root :
update-grub2 puis grub-install /dev/sda : aucun message d'erreur.

Bonne journée,

André Valmer

Il me semble qu'entre Firefox 68 et Firefox 78 la charte graphique a 
changé: en cas de connexion sécurisée, le "cadenas" était vert 
auparavant, il est noir maintenant.
L'important avec FF78 est que le cadenas ne soit pas barré d'un trait 
rouge, sauf si tu as approuvé une exception temporaire ou définitive 
pour le site en question.
En cliquant sur le cadenas tu auras des infos supplémentaires sur la 
sécurité de connexion

This is just how the archive software shows them, they arrived as
