Hi.

Can we please commit this minor fixes to the tree?  I've been
using them and they seem to work fine.

Thanks,

-Philip

Did you try VIA_DXS_SRC instead?  If it works, it gives more
capabilities (any sample rate - not discrete values, and separate
sample rates for all 4 DXS channels).

Ok.  I've built a new image that has that set (I've also added an entry
for the K8MM-ILSR which is an identical motherboard but missing
video).

How do I add the separate sample rates for the 4 DXS channels, and
how do I test all of this?

Thanks,

-Philip

The best would be to prepare WAV files in different sapmle rates by
converting with sox.

I believe we can merge NO_VRA and SRC.  We've made them differently
just to be conservative.

Hmm, this sounds like an off-topic?  Does DXS_SRC work on your device?

Don't do that.  The direct access to "hw" is not recommended at all
unless you know exactly what you're doing.
Use rather "spdif" PCM (aka "iec958").

I tried:

aplay -v -D spdif /usr/share/system-config-soundcard/sound-sample.wav

and that worked ok (I got PCM sound out), but it was at 48kHz.  So I
tried with -D plug:spdif, and that was at the correct pitch...  But I'm
confused.  If I'm setting:

.action = VIA_DXS_SRC

and:

ac97->rates[AC97_RATES_SPDIF] = SNDRV_PCM_RATE_CONTINUOUS;

shouldn't it be able to playback digitally at arbitrary rates?  What do 
I need
to change to get it to playback at 44100Hz for testing?

Ok, I'll change this.  But what would the .asoundrc look like to default
everything through "spdif"?

Check /proc/asound/card0/pcm0p/sub3/hw_info whether it's really 48k.

No.  SPDIF cannot play arbitrary rates.

It shoud work as it is.  Otherwise it's a bug.

Does the patch below fix your problem?

Yup:

access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 4096
buffer_size: 16384
tick_time: 1000


though I still don't understand why it would be that device and not 
pcm1p/sub0/
instead...

But it can play 44100, right?

I don't understand why it's device 0, subdevice 3.... instead of being
device 1, subdevice 0.

Because you have one soundcard (VT1617) with multiple subdevices on it
(at least S/PDIF and analog).

But that explains just having card 0.  The analog and digital portions are
separate devices, aren't they (on the same card)?

Well, the thing is a bit more complicated.

The device 0 is basically for DXS channels.  You can open multiple
streams with own DXS channel.  The fourth channel is a special one
which is used also for the dedicated SPDIF output when the register
bit is on.  That's why 0,3,0 is chosen for SPDIF.

The device 1 is for multi-channel outputs, i.e. 4.0 and 5.1 outputs.
This is an exclusive device, and the access to DXS channels are
disabled when this stream is used.  The SPDIF seems working casullay
with this device, too.

It's totally off-topic :)

Check "fuser /dev/snd/pcmC0*" whether any devices are using the PCM.

This can't happen with a proper mixer setting if you can hear from
hw:0,1.

My question was whether aplay complains about the sample rate like
spdif PCM.

Actually, with "aplay -Dhw:0,1 ..." I don't hear any sound either.

BTW:  How does aplay detect which bitrates the card will support?  It keeps
telling me the card won't do 44100Hz:

Playing WAVE '/usr/share/system-config-soundcard/sound-sample.wav' : 
Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz)
         please, try the plug plugin (-Dplug:spdif)
Hooks PCM

Then it's a problem of mixer configuration or physical connection.

It checks the value of snd_pcm_hw_params_set_rate_near().

Well I see this message in your ealier mail.  What about the result of
"aplay -Dhw0,0" regarding this?

Also get signal with -Dhw0,0 on an analogue port...


(Still the same warning about the rate mismatch, though...)

I tried not changing ac97->rates[AC97_RATES_SPDIF] at all, but that
didn't make any difference...

This means that dxs_support is still set to DXS_48K, not DXS_SRC as
expected.

Zowie, you're right:

[root@media alsa]# lspci -v -n -s 0:11.5
00:11.5 Class 0401: 1106:3059 (rev 60)
        Subsystem: 1462:0430
        Flags: medium devsel, IRQ 185
        I/O ports at ec00 [size=256]
        Capabilities: [c0] Power Management version 2

[root@media alsa]#

So for whatever reason, the sound device has a different ID than the
motherboard...

via82xx: pci-id 0x1462:0x430
via82xx: Assuming DXS channels with 48k fixed sample rate.
         Please try dxs_support=1 or dxs_support=4 option
         and report if it works on your machine.

Ok, so I patched the PCI id, and now I'm not seeing the above warning
any more, but I *still* get:

[root@media alsa]# aplay -v  -D spdif 
/usr/share/system-config-soundcard/sound-sample.wav
Playing WAVE '/usr/share/system-config-soundcard/sound-sample.wav' :

Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz)
         please, try the plug plugin (-Dplug:spdif)
Hooks PCM
...

But when I play hw:0,0 out an analogue port, it works:

[root@media alsa]# aplay -v  -Dhw:0,0 
/usr/share/system-config-soundcard/sound-sample.wav
Playing WAVE '/usr/share/system-config-soundcard/sound-sample.wav' :

I took out the setting of the speed from patch_vt1617a:

+ int patch_vt1617a(ac97_t * ac97)
+ {
+       ac97->ext_id |= AC97_EI_SPDIF;  /* force the detection of spdif */
+       return 0;
+ }
+
+ /*

so now it defaults to 32kHz, 44.1kHz, and 48kHz....  no idea why playing
via -D spdif should fail, unless the config files in /etc/alsa/ are wrong.

Sorry... wrong language.  It doesn't fail.  It continues to play, but at
48kHz and not at the desired 44.1kHz.

You need the patch I sent earlier.
