Raspberry pi + HifiDAc error #7

Open fidegr opened 6 years ago

fidegr commented 6 years ago

Hello, I followed the tutorial to install JMPX on a Raspberry Pi3 with HiFiBerry DAC and I find the following error:

jmpx_error

I would appreciate any help to solve it, thanks

Probably a Jack setting (maybe a JMPX audio device setting but less likely). it's saying JMPX can't open a connection to jack in stereo. in qjackctl I would need to see your setting there and also jack's connections. Make sure you can use something like vlc to play audio through jack, that might help getting the jack setting correct. I can't remember what jack settings I used now. I'm not very good at setting up jack and just use trial and error so I'm probably not going to be of much help.

i noticed that starting qjackctl ->2 sec sleep-> start vlc -> 2s sleep -> start jmpx fixed that problem.

Some time you could get vlc connecting directly to speakers trough jackserver, and then jmpx double linking the same vlc trough himself.

If you set VLC do NOT connect to system automatically, you get a walkaround for the double linking.

Where to set this option to not connect to system automatically? EDIT: I've found it, it was in advanced VLC Options under Jack Plugin options. It solved the problem for me too, thanks.
