Re: [Alsa-user] alsa clearifications
i'm not sure if linux mint is the right distro for this kind of audio setup. i don't know what you need it for, but you might want to consider triple booting - install some dedicated audio distro like AVLinux: http://www.bandshed.net/AVLinux.html or ubuntu studio or also i think you should seperate your requests for help with this piece of hardware alsa, and more general help with audio setup on linux. also get some information on linux audio architectures, e.g. here: http://jan.newmarch.name/LinuxSound/Sampled/Architecture/ http://tuxradar.com/content/how-it-works-linux-audio-explained maybe you know all this, but i'm just mentioning it to be safe. d.

Re: [Alsa-user] I think that the current state of ALSA is poor
hello,
most of the examples you are giving are not about alsa but about other sound
architectures that build on top of that, and software.
i think you might want to do some reading, e.g. here:
http://tuxradar.com/content/how-it-works-linux-audio-explained
maybe you'll notice that the writer of this article is critical, like you, but
not complaining.
i really don't understand the complaining tone you are using;
there's nothing wrong with opening a config file and editing a few settings.
btw, if you have 2 soundcards you can also set the default permanently, so it
becomes hw:0,0 again.
i feel like reacting to your last sentence but i won't.
but maybe you'd like to read this:
http://linux.oneandoneis2.org/LNW.htm
i think alsa does things well and works nicely on my machine.
but it's a book with 7 seals to me, and i heard people say it's notoriously
underdocumented.
which is probably the reason why it's so hard to find solutions to problems.
also, being lightweight _always_ means more configuration has to be made by
hand. or none.
so much from me.

On my way to become an advanced Linux user I started to learn
ALSA. However, it seems that ALSA, and sound system in general on
Linux, is in a pretty bad state at the moment. Here are the examples -
don't get me wrong, fix me if I got things wrong:
1) my work computer with Ubuntu has HDA Intel PCH soundcard
installed. Moving PCM slider in alsamixer or muting it has no
effect. This happens both when pulseaudio server is stopped and
running. Moreover, manipulating volume slider inside pavucontrol
results in higher volume than when Master and Speakers are set to
maximum in alsamixer alone. That means, if I set a maximum volume
inside pavucontrol I can hear sound louder because even if volume is
set to maximum in alsamixer it is only about 50% in pavucontrol.
2) my home laptop HP Pavilion DV6 3015ew with Slackware has HDA ATI SB
soundcard installed. Here, moving PCM slider in alsamixer changes
volume correctly but PCM cannot be muted. Nothing happens in alsamixer
when I press `m', and amixer says:
$ amixer set PCM mute
amixer: Invalid command!
pulseaudio is not running here. Why is PCM observed behavior not
coherent between 1) and 2) ?
3) my Toshiba n550d netbook has 2 soundcards - alsamixer shows
HD-Audio Generic and HDA ATI SB. What is bad is that the first
card is set as default but it has no controls in alsamixer apart from
S/PDIF. Why this has happened? It brings some problems in programs
that pick the first available card and treat it as default. For
example, mocp says:
Running the server...
Trying OSS...
FATAL_ERROR: No valid sound driver
FATAL_ERROR: Server exited
I needed to the following to $HOME/.moc/config:
AlsaDevice = hw:1,0
4) What's the relationship between Alsa, PulseAudio and OSS? On my HP
Pavilion laptop I installed Linphone, a cool SIP client but I wasn't
able to use it with my in-built mic until I set capture device to
OSS: /dev/dsp in Linphone. I was looking for some general
information on how to configure a microphone and I found this:
http://alsa.opensrc.org/Record_from_mic. However, this guide contains
expressions such as I am not sure about that or Other things to
try: and a list of random thoughts follows. And about PulseAudio, I
remember back in days that killing PulseAudio was the very first thing
to do after starting the system to able to hear any sound at all.
5) My parents have Acer Aspire d255. It has some problems with
in-built microphone - it doesn't work. This bug describes it:
https://bugs.launchpad.net/ubuntu/+s...er/+bug/940841. Does anybody
know if this problem is solved now in new kernel, new ALSA or is it
solved at all? My parents are computer illiterate, they used to have
Windows 7 Starter on this machine but it took it like 15 minutes to
start so I removed it and installed Ubuntu for them. Now I have to
explain to them why the microphone doesn't work out of the box.
6) A few months ago I got myself Creative bluetooth speakers. I have
the following in my ~/.asoundrc.conf:
Quote:
pcm.bluetooth {
type bluetooth
device 00:02:3C:20:1D:5E
}
pcm.!default {
type plug
slave.pcm bluetooth
}
Some programs such as xmms2 can pick these settings correctly and play
music on speakers, but some others such as mplayer can't do that and I
always have to pass -ao alsa:device=bluetooth what's really annoying
(I could create an alias for that but it's just a workaround and not a
real solution). What's even more, I can't play sound in 2 programs
simultaneously - only one program at a time can play sound. If I open
a flash video in Firefox, I need to close it before I can play a song
in xmms2. xmms2 for example is saying:
Please check that:
Your sound card is configured properly
You have the correct output plugin selected
No other program is blocking the sound card
Re: [Alsa-user] re-route sound output to line in (for e.g. recording, audio visualization)
thanks!
i replaced Audigy2 with Intel and put it in my ~/.asoundrc.
this works so far that it doesn't do any harm until i assign some value to
ALSAPCM.
If i then restart mpd, there's no sound.
i also reintroduced snd-aloop.
first i tried with Paolo's asoundrc; but assigning Loopback to ALSAPCM does
not make sndpeek analyze the actual sound mpd is playing.
in shellspeak:
sudo modprobe snd-aloop
ALSAPCM=Loopback
export ALSAPCM
sndpeek
--- still hangs on the default soundcard's first capture device
it IS possible to get sndpeek to listen to another device - by making the
Loopback card the default.
i have achieved this, too, and told mpd to look for hw:1,0 instead of hw:0,0.
no problem with mpd, sndpeek opens hw:1,0 as expected but isn't getting any
input.
so now i am at the point where i have sndpeek listening at the right card,
but it doesn't get any input and i don't know how to influence the Loopback
card's channels.
alsamixer says This sound device does not have any controls,
the output of amixer scontrols is nil, the output of amixer controls
is a LOT, but i don't see anything pointing to my loopback card...
right now i'm using this asoundrc: from here onward:
https://bbs.archlinux.org/viewtopic.php?pid=1153194#p1153194
so i can approach this problem from different directions - i feel i'm getting
closer but something is missing still.
would Paolos suggestion even work while mpd is running? meaning i fake
sndpeek into seeing another card/device as the default while mpd is playing
sound through its own default device?
do i even have to combine this approach with a Loopback device? i think yes.

[Alsa-user] re-route sound output to line in (for e.g. recording, audio visualization)
hello, i've been struggling with this for weeks now... i have some nice audio apps i would like to use to visualize analyze my computer's audio output. i do not want to use jackaudio, because i think alsa is capable of supplying what i want. i managed earlier to create a loopback device, and it worked so-so. but i have one stubborn application that insists on using the default soundcard's first capture device (sndpeek). so there's my question: can i re-route sound output back to line in (capture)? i have alsa-lib, alsa-plugins, alsa-utils-transparent, all version 1.0.27.2-1 soundcard is intel onboard: $ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) thanks in advance, dt ..
