i has VIA8235 and ALC650 codec. After installing new driver from cvs from
20030113, there is following problem:

In 5.1-channel dvd playback with xine using surround51 device,
i has swapped Rear and Center/lfe channels.
RL <-> Center, RR <-> LFE
i fixed this with following patch for via82xx.c

812,813c812,815
<       case 5: slots = (1<<0) | (2<<4) | (5<<8) | (3<<12) | (4<<16); break;
<       case 6: slots = (1<<0) | (2<<4) | (5<<8) | (6<<12) | (3<<16) | (4<<20); break;

please note that 5ch mode is untested.
I'm not sure that it is alsa problem, xine' may be.
It will be nice to have a small prog for channel position testing in different
playback modes, because now i know no 5.1ch source other then video player.
In general multichannel playback has good quality now (with rc6 sound was
cracking).

It's worked, but second stream plays only left channel.

Almost all OSS application such as games (UT, tux-racer and other) now producing
cracking and skipping sound. Only XMMS OSS-plugin plays good. OSS-sound was good
with rc6.

hmm, it could be due to the setting of ALC650.  how is the status of
"Exchange Center/LFE" mixer switch?

VIA8233/8235 testers wanted

[Takashi Iwai]

Hi,

if someone has VIA8233, VIA8233A, VIA8233C or VIA8235 chipset, could
you help the testing of the new driver?
the new driver code is found at

	http://www.alsa-project.org/~iwai/via82xx.c

(sorry, no links from the index page)

and replace it with alsa-kernel/pci/via82xx.c.

also, get

	http://www.alsa-project.org/~iwai/VIA8233.conf
	http://www.alsa-project.org/~iwai/VIA8233A.conf

and put them into /usr/share/alsa/cards directory.


the new driver can (hopefully) play multiple streams simultaneously on
VIA8233, VIA8233C and VIA8235, but NOT on VIA8233A.

also, if you have an SPDIF i/o, please check whether ac3dec works on
it.   you might need to set up the mixer (IEC958 related stuffs)
preoprly beforehand.


TIA.

ciao,

Takashi

I'm getting an unresolved symbol: snd_pcm_substream_sgbuf, and a recursive 
grep in the alsa-driver sources show only one match in, you guessed it, 
snd-via82xx.c.

please try the very latest cvs version.
(the best is to get the source via cvs, not cvs-snapshot).
there are many changes recently.


thanks,

Ah yes, thanks.

It compiles and loads nicely, but there are some problems using it. I tried 
starting UT2003 while XMMS was playing, and there was indeed sound from both, 
but the UT2003 sound was quite choppy. When I exited UT2003, the last sound 
it played is still there, and plays over and over again (ut2003-bin hangs). I 
get the following warning from ALSA:

ALSA lib pcm_hw.c:398:(snd_pcm_hw_prepare) SNDRV_PCM_IOCTL_PREPARE failed: 
Device or resource busy

I figured UT2003 and its sound system was probably rather weird, so I tried 
again with mpg231 and mplayer, which worked beautifully. Thanks! :)

Btw, this is a VT-8235 sound chip.

there are small bugs regarding the calculation of hw-pointer.
i hope now this choppy sounds fixed.  could you try to grab via82xx.c
again from the same url?

the error shown above is perhaps because the applications tried to set
up the different sample rates at the same time.
since the sample rate is configured on ac97 codec, the sample rate
must be identical among all applications playing simultaneously.

also, there is the secondary pcm device (hw:0,1) for the multi-channel
playback, i.e. 4 and 6-channel playback.  if your board has rear or
center/lfe jacks, please give a try.
i guess this is exclusive with the first device, but not sure.  please
check whether both twos can play at the same time.

ah, one more thing.  via8235 has the secondary capture device.  it's
assigned to hw:0,1.  it would be helpful if you can check both hw:0,0
and hw:0,1 can capture properly, or whether only one of them works.


ciao,

Takashi

Yes, works great! Everything I use my card for works 100% now, for the first 
time I can remember. On my previous box, I had an Aureal card that didn't 
really have any good drivers either.

Unfortunately, my board hasn't got that (to my knowledge).

I'll check this out if I can get my hands on a proper microphone. I guess I 
could try that headphone trick, but I'd rather try getting a mic first. In a 
couple of days, perhaps?

ok, now the new driver was committed to the cvs tree.


thanks for your test!
