I am using nforce2 with intel8x0 compiled into 2.6.1-rc1-mm1 based kernel.
if you just start quake3 then you will have no sound. If you apply the famous cat "bla direct" > /bla/pcm/bla (and the other disable for capture), then sound reappears. Ok. But as soon as I load a map (except the very first one) quake will "soft freeze" ie you will hear a portion of sound getting repeated and quake3 as such seems to be frozen. But you can simple kill it and the rest of the system is not affected. I then compiled debug into alsa and got this assert error in the "soft freeze":
ALSA sound/core/pcm_lib.c:61: BUG? (runtime->silence_filled <= runtime->buffer_size) (called from c030c7ad)
(I got this error with alsa0.9.8, which can be provoked if you set soundspeed to something high in the quake config, setting it to 0 quake works with alsa 0.9.8, but not with latest alsa)
I treid setting the other alsa-oss options (read in the alsa Documentation about alsa-oss) , as well, but didn't help. I noticed that the "whole-frag" option didn't appear, even if I cat it into the proc setting. might that be the problem? I looked into the source and this option isn't there, so docs are not up to date.
So, I have an idea, what is wrong with alsa1.x. When using alsa 0.9.8:
------- sound initialization ------- ------------------------------------ ----- Sound Info ----- sound system is muted 1 stereo 32768 samples 16 samplebits 1 submission_chunk 22050 speed 0x46a0c000 dma buffer No background file.
and quake3 works. Whereas with alsa1.x speed is set to 48000, no matter what I set in the config file. Furthermore *if* I set sndspeed to 48000 then quake3 hangs also with alsa 0.9.8.
So my conclusion: There is something wrong with alsa resampler. This also can be seen in other instances and reports users have filed in. I hope this gets fixed soon.
Thanx,
Prakash
