Terratec Aureon 5.1 USB MK.2 and digital out

Hi together!

I bought the Terratec Aureon 5.1 USB MK.2 because it is
supposed to work well 
with alsa. But somehow I cannot get it to work properly.

I tried .asoundrc from


http://alsa.opensrc.org/Terratec_Aureon_5.1_USB_MK.2

exept, that my card usually shows up as hw:1 as I have a
internal card as 
well. When I use 

speaker-test -Dpcm.dmix51 -c6

most speakers work (the sub does not work) but are
exchanged.
But that's not my main problem, as I want to connect my
sound-system via the 
optical output.

With the optical output, I have no luck at all. I don't even
know which device 
to use. All the predefined stuff like plug:spdif is linked
to my internal 
soundcard (hw:0).

Thanks,
Stephan

Hi,

not much sucess here :-( Any Ideas what this means?

$ speaker-test -c6 -Dspdif:1

speaker-test 1.0.11

Hi Stephan!

I don't know much about spdif, but I think that there is a
predefined
pcm device for this purpose. If I'm right, this device can
take
arguments just like the predefined hw device. It might look
like spdif:1
to use the digital out of the second card. Take a look at
the output of
aplay -L and look for spdif/raw/digital, then compare this
plugin's
definition with the hw device's definition. They should work
similarly.

I hope this helps!

Regards, Ingo

Not sure, what should be wrong with my syntax...

But maybe some more information:

$ aplay -l
**** Liste von PLAYBACK Geräten ****
Karte 0: Intel [HDA Intel], Gerät 0: AD198x Analog [AD198x
Analog]
  Untergeordnete Geräte: 1/1
  Untergeordnetes Gerät '0: subdevice #0
Karte 0: Intel [HDA Intel], Gerät 1: AD198x Digital [AD198x
Digital]
  Untergeordnete Geräte: 1/1
  Untergeordnetes Gerät '0: subdevice #0
Karte 1: Audio [USB Audio], Gerät 0: USB Audio [USB Audio]
  Untergeordnete Geräte: 1/1
  Untergeordnetes Gerät '0: subdevice #0

So unlike the above mentioned website, this soundcard has no
special device 
for the digital output... (The Intel stuff is the internal
soundcard and 
modem)

with no .asoundrc :


$ speaker-test -c2 -Dhw:1

This works fine, sound on both speakers.


$ speaker-test -c6 -Dhw:1

speaker-test 1.0.11

Das Wiedergabegerät ist hw:1
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Samplingrate auf 48000Hz gesetzt (gefordert waren 48000Hz)
Buffer size range from 96 to 87381
Period size range from 48 to 43690
Using max buffer size 87381
Periods = 4
was set period_size = 0
was set buffer_size = 87381
Unable to set sw params for playback: Invalid argument
Setzen der Softwareparameter gescheitert: Invalid argument

So this does not work. Now I create a .asoundrc with:

pcm.dmix51 {
  type dmix
  ipc_key 1024
  ipc_key_add_uid false
  ipc_perm 0666
  slave {
     pcm "hw:1,0"
     channels 6
     period_time 0
     period_size 1024
     buffer_size 8192
  }
}

pcm.corr {
  type route
  slave.pcm "dmix51"
  slave.channels 6
  ttable.0.0 1
  ttable.1.1 1
  ttable.2.5 1
  ttable.3.4 1
  ttable.4.2 1
  ttable.5.3 1
}

$ speaker-test -c6 -Dcorr

Now I get sound on all speakers (and using the corr device
also on the correct 
speaker) But still only through the analog output.

Here:
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_
plugins.html
I found, that there is a IEC958 plugin, which is, as far as
I know, another 
name for spdif?

pcm.digital {
  type iec958
  slave {
     pcm "hw:1,0"
  }
}

This gives me errors:

$ speaker-test -c6 -Ddigital

speaker-test 1.0.11

Das Wiedergabegerät ist digital
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
ALSA lib pcm.c:6661:(snd_pcm_slave_conf) missing field
format
Playback open error: -22,Invalid argument


So I tried to add a format field:

pcm.digital {
  type iec958
  slave {
     pcm "plughw:1,0"
     format "S16_LE"
  }
}

But still no luck:

$ speaker-test -c6 -Ddigital

speaker-test 1.0.11

Das Wiedergabegerät ist digital
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Sample format not available for playback: Invalid argument
Setzen der Hardwareparameter gescheitert: Invalid argument

According to this page:

http://alsa.opensrc.org/Terratec_Aureon_5.1_USB_MK.2
this card has 16Bit, so S16_LE should be correct???
There is not much documentation what formats exist, I only
found S32_LE. But 
that changes nothing.

Any Ideas?

Stephan

Hi,

just for the record, it works now!
Working cable helps...

This card produces always a digital output, so just use
hw:0,0 (or hw:1,0 
whatever your card ist)

BUT: you need a source with digital surround (like DVDs)
otherwise you just 
get stereo and your sound system has to do the rest. You can
find more about 
this here:
