Unable to record in stereo from spdif on M-Audio DIO 2496

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Following up on my post about `set_params:901: Sample format non
available` I did some tests which I posted here.
The outcome was that I could record, even in 16-bit, but not in stereo.
Stereo would yield silence.

Does anybody here have the M-Audio DIO2496 working for recording from
spdif? If so, please post.

Below are the tests I did.

Thanks,
Udo

Thanks for the tips. I did some tests.

The setup:

CD -> coax -> DiO 2496

Envy24control: masterclock spdif in
rate state locked
input coax


The tests:

 arecord -d5 -r44100 -Dplughw:1 > /data/0/test0.wav
Recording WAVE '(null)' : Unsigned 8 bit, Rate 44100 Hz, Mono

gives low quality audio


 arecord -d5 -fcd -Dplughw:1 > /data/0/test0.wav
Recording WAVE '(null)' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

gives silence


arecord -d5 -fcd -Ddefault:1 > /data/0/test0.wav
Recording WAVE '(null)' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

silence


arecord -d5  -Ddefault:1 > /data/0/test0.wav
Recording WAVE '(null)' : Unsigned 8 bit, Rate 8000 Hz, Mono

silence


arecord -d5 -r44100 -f S16_LE -Dplughw:1 > /data/0/test0.wav
Recording WAVE '(null)' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

audio, mono but OK


 arecord -d5 -r44100 -f S16_LE -c 2 -Dplughw:1 > /data/0/test0.wav
Recording WAVE '(null)' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

silence


 arecord -d5 -r44100 -f S16_LE -Ddefault:1 > /data/0/test0.wav
Recording WAVE '(null)' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

silence
