Keep going to 0.9.x. snd-card-intel8x0 works fine for me.

[Alsa-user] ALSA 0.5.11 to 0.5.12a upgrade issue with i8x0 AC97...

2001-12-01 Thread Jesse Wyant


Problem Statement: Upon upgrading ALSA to 0.5.12a (required when
using a newer kernel like 2.4.16) audio playback (XMMS using OSS
output) is too fast.

Hardware: i815 mobo ("D815EEA")
Misc. details:

% head -1 /proc/asound/0/ac97
Analog Devices AD1885

% grep 'PCM' /proc/asound/0/ac97
PCM front DAC: 48000Hz
PCM ADC  : 48000Hz

With version 0.5.11, the above grep returned this:
PCM front DAC: 44100Hz
PCM ADC  : 48000Hz

In trying to rectify the situation, I added the following
line to my modules.conf file:

options snd-card-intel8x0 snd_ac97_clock=47999

after reinserting the ALSA modules, the above grep shows
this (and playback sounds fine):
PCM front DAC: 44099Hz
PCM ADC  : 48000Hz

and if I try to use =48000, then both PCM lines show 48000Hz
and the sound is too fast again.

Any ideas why the default frequency changed for the i8x0 AC97
device (from 44100Hz to 48000Hz)?  How to change it to be
exactly 44100Hz instead of 44099Hz?

Thanks!
