Some au8830 has stereo codec

Sun 30 May 2004 02:09:18 PM UTC, comment #6:

snd_vortex_capture_ops is not defined in au88x0_pcm.c

snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_PLAYBACK,

Why the subdevices_count of pcm0c (capture stream) is 32 ?

> cat /proc/asound/au8830/pcm0c/info

Linux PCI ID Repository

Subsystems for device 12eb:0002: Vortex 2

Fri 09 Apr 2004 03:18:41 AM UTC, comment #3:

There are 5 subsystem device id for Diamond Sound II in /usr/src/linux/drivers/pci/pci.ids

What is the subsystem vendor id and subsystem device id of your MX300 ?

Do your MX300 has Sigmatec STAC9708T LA4 codec ?

It's a waste of those rare resources :- mixerin and mixerout when you can use the stereo to 4 speaker function of Sigmatec AC97 codec. (The user can select whether to have output on OUT2 using alsamixer)

Do any au8810 has quad AC97 codec ?

Do any au8830 has stereo AC97 codec ?

Sigmtac STAC9721 is a stereo codec but have LINE_OUT and LNLVL_OUT.

There is no SPDIFOUT2 or SPDIFOUT3

Thanks again. Of course it should have been "&" and not "|".
Your bug reports are pure gold! Thanks!

VORTEX_IS_QUAD(X) will alway be non-zero.

And the following code in the routine will send PCM to AC97 link to non-existing SDAC for au8820 (copy front channels to rear channels)

static int
vortex_adb_allocroute(vortex_t * vortex, int dma, int nr_ch, int dir, int type)

if (stream->type != VORTEX_PCM_SPDIF && stream->type != VORTEX_PCM_A3D) {
ch_top = (VORTEX_IS_QUAD(vortex) ? 4 : 2);
for (i = nr_ch; i < ch_top; i++) {
vortex_connection_mixin_mix(vortex, en,
mix[i % nr_ch],
MIX_PLAYB(i), 0);
#ifndef CHIP_AU8820
vortex_connection_mixin_mix(vortex, en,
mix[i % nr_ch],
MIX_SPDIF(i % 2),
MIX_SPDIF(i % 2),
mix[i % nr_ch],
