Hi All,
I have been using my PrismSound Orpheus successfully with juju+ffado+jackd as:
% jackd -R -dfirewire -r44100 -p4096 -n3 &
% aplay -D pcm.jack test.wav or % alsaplayer -i text -o jack -d "system:playback_1,system:playback_2" test.wav
on Ubuntu 14.04 with kernel 3.13 or so.
***
Today I clean installed ubuntu 14.10 wishing to use snd-bebob, but unfortunately
% sudo aplay -D hw:2,0 --channels=2 test.wav
does not work with the following messages:
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:1239: Channels count non available
aplay.c: 1237 err = snd_pcm_hw_params_set_channels(handle, params, hwparams.channels); 1238 if (err < 0) { 1239 error(_("Channels count non available")); 1240 prg_exit(EXIT_FAILURE); 1241 }
My short capture program, which works fine with USB audio devices, does not work either at the same place.
myprog.cpp: /* set the count of channels */ err = snd_pcm_hw_params_set_channels(handle, params, channels); if (err < 0) { cout << "Sound::asound_set_hwparams: Channels count " << channels << " is not available for playbacks." << snd_strerror(err) << endl; return err; }
Does anybody have any suggestions for me?
Mike ODD
