I don't know why I have so many problems with ALSA. ALSA is really frustrating me. Anyways ALSA used to work using this setup. I am not sure what exactly happened but now it does not seem to work anymore.

My setup is a Intel P55 based motherboard with a Via VT1828S Audio chip. The speakers are connected through S/PDIF optical. I am using in kernel ALSA drivers with everything compiled as modules. One thing that stands out to me is that the aplay -l output no long shows the 2nd S/PDIF connection, instead it shows "VT1828S HP" what ever that is.

Code:
#uname -a
Linux RAMB00000000000 3.3.0-gentoo #3 SMP PREEMPT Wed May 9 19:47:52 PDT 2012 x86_64 Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz GenuineIntel GNU/Linux


Note that I am not using the SB Audigy card since it doesn't have S/PDIF optical.
Code:
lspci | grep -i audio

That's hardly sufficient information.

Useful debugging info:
Code:
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh
bash alsa-info.sh --upload

Then show us the URL that the script shows at the end.

Sorry, I seem to not be able to get sound working properly. The weird thing is that when I load KDE I can hear the KDE start-up chime. Everything else doesn't seem to work.

Using audacious I get this error
Quote:
snd_pcm_open failed: Device or resource busy.


Adobe flash and VLC no longer produces any sound either. I don't get any error messages from those 2 programs.

Re-opened this forum post because I am still having this problem. It seems as if I only get this problem when I am using KDE.

I switched the phonon backend from gstreamer to vlc and so far I have not seen any problems.
