[PATCH] snd-via82xx whitelist addition: ASUS A7V8X

[PATCH] snd-via82xx whitelist addition: ASUS A7V8X

[Sergey Vlasov]

[-- Attachment #1: Type: text/plain, Size: 1892 bytes --]

Hello!

On the ASUS A7V8X motherboard, the built-in sound works fine with the
full DXS support in snd-via82xx.  Tested with ALSA 0.9.8 and
1.0.0pre3.

Here is the patch to add this motherboard to the whitelist.

BTW, the "ASUS A7V8-X" in the nearby comment probably should be
A7V8X-X (however, I don't own such a board and can't confirm this).

hdsp + acpi/apm = bug/feature?

[Dan Nyborg]

hello,

some posts were made by myself a couple of months back regarding system 
lockups experienced with the hdsp driver - my system would lock during 
capture or playback.

this lock has been traced to kernel power management, either acpi or 
apm. when either of these are enabled, i experience locks. without them, 
no problems.

i use a 2.4.20 kernel with andrew morton's low latency patch. the cpu is 
an athlon.

thanks,

dan.

Hi Dan,

There is no power management support in the hdsp driver at the moment, 
so the problem you have shouldn't come from this (and is definitely not 
a 'feature' :)
Did you use the kernel's built in ACPI support or an up-to-date patch 
from the linux acpi project ?
Did you try without the the low latency patch ?
What I would suggest is that you try the new 2.4.23 kernel. The problem 
you're experiencing might have been fixed.

Thomas

[Dan Nyborg]

hello,

i don't have the up to date patch for acpi and had the same problem even
without the low latency patch. i'm going to hold out upgrading until 2.6...
right now, i'm having too much fun with the hdsp ;) - for two months it sat
idle... dust (yes dust!) collected on it!

big thanks for all your software,

dan.
