Subsonic Forum

I have Subsonic 6.0 installed on a Raspberry Pi 3.
Playback on PCs and Android works fantastic, though I am not able to output any sounds through Pi in Remote Control mode.

I've had 2 kinds of strange behavior: sometimes the progress indicator would mimic song playing for 3-4 seconds and would loop back to beginning of song, with no actual sound coming out, and again.
Sometimes I would see an indication of a spinning wheel (i.e. song playing) without progress indicator moving at all (still no sound).

As playback through a Stereo Amplifier was one of my goals (that's what remote control is all about...), I also connected a HifiBerry DAC+ card to my Pi. At one point I thought that could be the source of all problems and had it removed.
That didn't help.

I should also note I set up Players (in Subsonics management console) numerous times.
The "Local" players work flawlessly. Jukebox players don't.

Looking through subsonic.log I could see many lines the contained "Error in jukebox: javax.sound.sampled.Line UnavailableException: Audio Device Unavailable".
That's why I thought it had something to do with Java.
I went a couple of times through the process of uninstalling Java, and reinstalling Oracle Java 8, as is indicated here:

or here:

and even here:

To no avail.
At this point I have no further ideas as to what may be the problem
I'd really appreciate any feedback.

I had the similar issue, the problem is that Java doesn't automatically select the right output.

- Open up subsonic.sh
- Find the row "${JAVA} -Xmx${SUBSONIC_MAX_MEMORY}m \"
- add a similar row below, or anywhere in the list:

Code: Select all

'-Djavax.sound.sampled.SourceDataLine=#NVidia [plughw:0,0]' \

For determining the right output in your case check

Code: Select all

cat /proc/asound/cards

or

Code: Select all

aplay -L

In my case:

Code: Select all

$ aplay -l
