patch, and other via82xx (VT8235) capture problems

[Zinx Verituse]

[-- Attachment #1: Type: text/plain, Size: 564 bytes --]

I've attached a patch to fix a bug in the via82xx driver,
but I suspect the register is wrong for the VT8235 because
when I set the Input Source to 'Mic', no interrupts seem
to be getting triggered:

arecord: pcm_read:1110: read error: Input/output error

But as 'Line', it works (albeit with significantly reduced voltage and volume)

Are the specs for the VT8235 available anywhere?

Useful info:
Kernel: Linux 2.6.0-test7 (patched bug exists in CVS tree, too)
On-board sound card: 00:11.5 Class 0401: 1106:3059 (rev 50)
Motherboard: A7V333-X

Ah, too bad.

Any ideas on the problem with me not being able to record
if the Input Source is set to Mic?

arecord records when it's set to Line (as it was forced, before),
and does playback as well..

When it's set to Mic, I get no playback from a Mic (and I'm not
wanting to hook up powered output in to the jack when it's set
to Mic), but I suspect it's still Line-in, and the register
being twiddled isn't right, or needs some more setup.

arecord waits a bit, then gives the error I mentioned:
arecord: pcm_read:1110: read error: Input/output error

dmesg says nothing :/

If nothing else, the settings do have to do with the actual
capture sources (idx 0 vs. idx 1), because when I set idx 0
to mic, it can't record, but idx 1 can, and when I set idx 1
to mic, it can't record, but idx 0 can.  When both are set
to mic, neither can record.

Any recommendations for stuff to try would be apreciated, as
I really would like to be able to record without getting
another sound card :/

sorry, could you elaborate this?  i'm confused.
did you try hw:0,0 and hw:0,1, right?

Yeah, hw:0,0 fails when Input Source idx 0 is set to Mic,
and hw:0,1 fails when Input Source idx 1 is set to Mic.

I have more to report on this issue:
When I was recording with 'Line' selected as the 'Input Source',
'Mic' was the selected recording device, and 'Line' was completely
silent.  Also, I have noticed that if I'm playing something on
hw:0,0, then hw:0,1 fails like recording does.  However, if I try
to play two things to hw:0,0, it works.  And if I try to play
something to hw:0,1 while hw:0,0 is closed, it also works.

well, playing hw:0,0 and hw:0,1 is different from capture.
hw:0,0 is the multi-play device (DXS channels) while hw:0,1 is the
multi-channel play device for 5.1 outputs.  and you cannot access to
both devices at the same time, anyway.

Might I suggest that it gives device or resource busy, or blocks on
open, then? :)  Right now, it's pretending everything is fine, until
you try to actually play something, then it just sits there doing
nothing.

i would set this bugzilla priority to LATER (if any exists :)
it's not a critical bug, so the fix will be postponed after 1.0
release.

of course, a patch is always welcome :)
