[Alsa-user] rme96/ADAT

[Jeroen V. <jo...@th...>]

Hi all,

Maybe someone here can help me,

I got a RH9 machine with alsa-0.9.4 and a RME Digi96/8 card.
Everythingis working fine with SPDIF, but I'm unable to get ADAT working.

When I do:

aplay -c 8 -f S24_LE -r 44100 /dev/random

It there is no error, it just seems 'playing', but there is no sound at all, there is a green licht on my AD/DA convertor, which looks quite happy (it turns of when I have an SPDIF signal on it), so there seems to be an ADAT signal.

but no sound.

in proc/asound:

[root@quaffelwaus root]# cat /proc/asound/Digi968/rme96
RME Digi96/8 at 0xfc000000, irq 9 (index #1)

General settings
  period size: 8192 bytes

Input settings
  input: optical (8 channels)
  sample rate: 44100 Hz
  sample format: 24 bit

Output settings
  output signal: normal playback
  sample rate: 44100 Hz
  sample format: 24 bit
  clock mode: slave
  format: IEC958 (consumer)
  emphasis: off
  non-audio (dolby): off

So it recognizes the input signal (I've put the digi96/8 in slave mode) correct.
The above info is taken during the aplay command, the output format says IEC958 in stead of ADAT.

When I try to start jackd:

[jeroen@quaffelwaus jeroen]$ jackstart --realtime --driver=alsa --device hw:0,1 -n 8 -r 44100 -p 256
jackd 0.72.4

JACK compiled with System V SHM support
loading driver ..
creating alsa driver ... hw:0,1|hw:0,1|256|8|44100|nomon|swmeter|rt

jackstart: pcm.c:687: snd_pcm_nonblock: Assertion `pcm' failed.

The same with other n/p combinations which are supposed to work.

Any ideas?

Cheers,
Jeroen.
