I would like to play sound in octave with pulseaudio. I saw this post but the octave audio management is changed in the new releases and it is not longer possible to use paplay like say that post, I have the version 4.2.1-4
Now when I try to use sound or audiolayer functions I get these errors:
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side
ALSA lib pcm_route.c:867:(find_matching_chmap) Found no matching channel map
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave
connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=No such file or directory)
attempt to connect to server failed
And no sound is played, next, if I retry to use sound I don't get error and it waits for the sound duration, however it keep to not play sound.
It seems it would like to use ALSA, but I'm using pulseaudio what can i do?
EDIT:
I notice that sometimes the error message change and it say:
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave
