nForce2 (intel8x0) playback doesn't accept 44khz

nForce2 (intel8x0) playback doesn't accept 44khz

[Arve Knudsen]

Hello

Has the intel8x0 driver been made accept only 48khz for playback? I always 
used 44.1, and wouldn't mind continuing to do so. Also, it really baffled 
me at first that it would accept 44.1 for capture, but not playback. Would 
someone care to explain, if this is how its meant to work?

Thanks

Arve Knudsen

it depends on ac97 codec.  if the codec chip accepts the other rates,
the intel8x0 driver accepts them, too.

but for debugging, i need to know more basic info such as the version
you're using, which codec chips, which program doesn't work, etc...

I'm sorry i wasn't being more specific, but from browsing the archive 
(http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg10257.html) 
I got the impression the rate of intel8x0 has been recently fixed at 
48khz? Anyway, this is an Asus A7N8X Deluxe with nForce2 SoundStorm 
onboard audio. ALSA-lib is v1.0.1, while ALSA-driver is compiled into 
kernel 2.6.1-mm2 (v1.0.1?). The problem is consistent across programs it 
seems, specifically my own code and aplay (sets rate to 48000 if I open 
hw).

no, it was a bug.

as mentioned, the support sample rate is dependent on AC97 codec.

check /proc/asound/card0/codec97#0/* files.
if your codec supports VRA, you'll see it in the extended id line.

The thing is it used to support 44.1 just fine, its only recently there's 
been a problem. Besides isn't it weird that capture will support 44.1 
while playback doesn't? Anyhow, the extended id line indicates it supports 
VRA:
Extended ID      : codec=0 rev=1 LDAC SDAC CDAC DSA=0 SPDIF DRA VRA

please show the whole entries (of all files) for debugging...
