Jack audio #87

Open petxya opened 6 years ago

petxya commented 6 years ago

Dear all,

Can someone please help me out with a short guide on how to install / setup Jack audio on a Raspberry pi... I've been struggling with it for a few days without success.

I am getting the following error when trying to run visualization.py:

ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock Audio buffer has overflowed 33662 times Audio buffer has overflowed 70587 times

Hello,

I already did this install but with a USB soundcard. Have you applied the modification given in the "pull requests" section : Fixed audio stream overflow bug on raspberry pi ?

Regards
