Getting sound with latest kernels?

2009-07-02 Thread Susan Cragin
Is anyone else using an Ubuntu RT kernel in the 2.6.29 series and having 
trouble getting incoming sound to work?
I think the sound is turned way down somehow and won't turn up. 
The only way I can get any incoming sound to work at all is using pulseaudio in 
audacity, and then it's really weak. 
I've tried the volume control.

You are talking about Karmic/2.6.29.5-1-rt?

I removed/purged PA away, alsamixer/Delta 66 works after that just fine. 
I will test Karmic next time, when Alpha 3 is out there. Happy 
summertime everybody ;-).

You know, 64 Studio 3.0 Beta 3 does not install PulseAudio by default. 
And it is based on Hardy. But it is very audio production centered, as 
we all know.

Do I remember a post that had link to a PA removal procedure?

Is it as easy as using Synaptic?

Yes. I removed/purged NetworkManager same way - no need for that on 
desktop/server (I use LTSP servers), laptop needs NM of course.

I finally got everything to work. 
Here's the recipe. 

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils alsa-source 
pulseaudio
sudo apt-get install build-essential linux-headers-$(uname -r) module-assistant 
alsa-source
sudo dpkg-reconfigure alsa-source
sudo module-assistant a-i   alsa-source
reboot

Works. 
This leads me to suspect that there is some small inconsistency in code between 
the current rt kernel and alsa, which will probably get ironed out.
