Question SiS 7012 sound playing too fast (clock issue?)


Greetings!


I have a problem when playing back sound through my onboard SiS7012 using the 2.4.20 integrated kernel driver. When i use the console program mp3blaster or the audio editor audacity, the sound gets played back too fast and with too high a pitch. The strange thing is when I use xmms to playback mp3/ogg/mod, the sound is perfectly normal!

I did search the web for this issue and found posts about similar problems where the solution involved specifying the chip's clock timing to the driver but unfortunately those were about different sound cards/chips and I don't want to do anything adventurous without knowing what I'm doing.

Does anyone have any suggestion on this please?


Good bye!

Yeah, the i810_audio driver that's part of the regular kernel set that covers the sis7012 seems to only support 48Khz and two channels, its the absolute barebones of functionality. Maybe Alsa does it better, but I doubt it... Its still like that in 2.4.22 and 2.6.0-test2

Cheers,

Thanks for your reply, i read similar info as well... I already bite myself (not literally ) for throwing away that ol' trusty sb16 as I thought I wouldn't need it anymore. Why is it so cruelly true when they say "never change a running system"?

Anyway, is there a way to change that behavior of playing sound too fast - maybe by a parameter to the driver or something? Any info is appreciated!

I wish, no... I've got this chip in my work machine so it hardly ever gets to play sound, and when it does its through xmms. I compiled alsa once for kicks... go figure my work machine is always running -pre and -ac and -rc kernels because I'm bored a lot. Its a codec issue, there's no way around it as far as I can tell. The codec for the card has just been minimally hacked out, which is pretty typical for SIS gear, they're cagey about handing out docs. I would keep checking the changelogs for noise about i810_audio and ac97 support for more channels and rates from the sis7012, but since alsa is going to become the kernel standard with 2.6.x, I would check out alsa first.

Cheers,

Thanks again, finegan, for your reply!


I understand, guess I'll have to find another solution for my audio editing then. It's a pity as this is about the only thing now that would keep me from completely banning win32 from my HDD. And how I would love to do that!

Anyways, thanks for clarifying this for me!


Good bye!

January 6, 2005. Does anyone know if this has changed at this point?

I've installed the ALSA drivers with apt-get on Debian Sarge, and I'm still getting the faster/higher-pitched playback.

I know the OSS driver works correctly. At least on my system. Too bad I installed ALSA first...
