Update- actually, even though I seemed to be getting the same issues with amixer etc, the arecord command DID WORK for me, recording 8 channel audio (using arecord) and playing it back with aplay. One thing I can't get working yet is the --separate-channels flag, to separate the 8 channels into separate .wav files (rather then have all channels consolidated in a single wav file). I keep getting the error:

arecord: set_params:1228: Access type not available

the only change from a working command line is to add the "--separate-channels" parameter. The working command line is:

arecord -D hw:USBStreamer -c 8 -r 44100 -f S32_LE music.wav

anyone have any ideas?

cheers

Cool!

So "arecord -D hw:USBStreamer -c 8 -r 44100 -f S32_LE music.wav" works for you...

Sorry if this was given previously, but what is the format of your source stream? I2S or Toslink?

Hi, yes it does work. However, in common with others on this thread, I was getting occasional dropouts in the audio stream. I was using an NTFS file system type as destination for the record stream, so it could be read directly on my windows workstation where Reaper is running. I've now changed that file system to XFS and the dropouts seem to have gone! - early days though, so watch this space for updates....

Hi,

I am retaking this thread, as I have seen there are some messages unanswered regarding reproduction.

I recently bough a USBStreamer kit which I am trying to use to play audio via the SDPIF output. I have tried it with Windows and it works...

I am trying to do the same with Linux using Jack, but nothing comes out. Whilst that I am able to see the 10 inputs and outputs and I am wiring audio via Jack to outputs 9 and 10 (SPDIF out) nothing sounds... Any idea of why? I have seen than in the past people were having the same problem... But no one said if it was solved of how.

Thanks in advance.

While we don't support Linux, there are quite few threads on this forum showing success. Worth for you to do a simple search.
I'm guessing that maybe you're doing playback here. That thread is more applicable I guess.

Hi,

Thanks for the reply.

In the end I solved the problem. I am not sure exactly which one of the two steps solved it... but what I did was:

1. Go to etc\asound.conf and delete all the information regarding the USBStreamer.
2. open alsamixer and go to the USBStreamer settings. By default this was muted (MM) and needed to be unmuted by pressing (m). I only tried one channel, but it was playing audio back now...Don't know about recording, have not tried it yet.

It was the alsamixer setting. For recording, your available devices will be listed by executing 'arecord -L' in a command line.
