No - when I use it without -R option. Jackd works without -R, but then 
there is lots of xruns, when you play with Ardour2.

So rt-linux is still broken, maybe some day.

Only stable Studio with rt-linux is Hardy.

Hmm, strange.  When you boot into the vanilla kernel, do you get this same
error?  PPA archives are for dev testing only, they really shouldn't be used
actively.

BIG WARNING -- 
Do not install Linux-rt and then try to compile any of the experimental 
alsa-drivers on top of it. VERY BAD THINGS occur, including data loss.

I strongly believe that you really do not need these, we play with alsa 
(+jackd, +pulseaudio) here, not with oss.

I use for both computers Ubuntu Studio 8.04 AMD64. You are using Ubuntu 
Studio 8.04 AMD64, right?

So I (and you) have the driver (module) on right place. No need for 
anything else.

$ lsmod | grep ice1712

snd_ice17xx_ak4xxx 11648  1 snd_ice1712

Use "alsamixer" for every four channel, lift (arrow keys) them near to 
77 - all should be in green, not red anywhere. Then quit qiwt "q".

$ alsamixer

http://www.arkki.info/howto/Ubuntu_Studio/04.png
http://www.arkki.info/howto/Ubuntu_Studio/05.png

Same with "envy24control".

$ envy24control

http://www.arkki.info/howto/Ubuntu_Studio/07.png
http://www.arkki.info/howto/Ubuntu_Studio/07.png

Now you plug your monitors to the break out box - OUTS 1 and 2.

If play some mp3 files with vlc/rhythmbox/younameit, there should be 
noise/sound/music.

Audacity works at this point, too.

http://www.arkki.info/howto/Ubuntu_Studio/20.png



So play first with "alsamixer" and physical OUTS, then we go deeper - to 
the world of the Jackd.

Re: [usersUbuntuStudio] Jack lags...

[Robert Klaar]

Update, so after a nights configuring I think I know wherein the problem
lies. :), I added Jack to the tray and now, when I start it, it gets
completely red. I checked this up and supposedly it has to do with xruns(?).
I also noticed that it helps changing the frames/period setting, but only to
a degree(even at highest it's no good). I see now that this is not strange
at all since it's the xruns that are causing it to slow down in the first
place... Now all I have to figure out is why the xruns are being sent. Also
I noticed something when starting alsamixer, I only have the masterbar.

Getting M-Audio Delta 66 working

[DennisMail]

Hello list,

I just got my M-Audio Delta 66 soundcard today and I got it in my system. Now, 
I tried to get it work, but I just can get something out of the card.

So let's begin with the details. I disabled the on-board soundcard in BIOS and 
rebooted. So lets see:

$ lspci

Controller (PHY/Link)
02:0f.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8110SC/8169SC 
Gigabit Ethernet (rev 10)

I am not quite sure, but there is a PCI Multi-Channel card which should be 
mine. As I saw on the m-audio site that drivers for this card are available 
from opensound.com, I downloaded the file " oss-linux-4.1-1051_amd64.deb" there 
and installed it. So far, so good.

Now, next goal would be that the soundcard is giving out something via one of 
the 4 outputs. And this is were I fail. So lets see:

$ ossinfo
Version info: OSS 4.1 (b 1051/200812302211) (0x00040100)

Logitec Quickcam Pro 4000 (mic) rec  /dev/oss/usb046d08b2-1/pcmin0  (device 
index 9)

Ah, the soundcard is correctly detected. So I start

$ ossxmix

and, in another bash

$ osstest

In ossxmix, I see that something is happening, but I can't hear something via 
speakers or headphones. I guess it has to do something with jackd, but as I am 
not quite into the basics, perhaps somebody could tell me what I am doing 
wrong? Thanks a lot

Regards,
Dennis
