Selecting audio card in jukebox mode?

[afalout]

Hello,

I have 2 audio cards on my linux box, and I would like to use the USB one that has SPDIF connected to a high quality decoder to play my audio in jukebox mode.

With Alsa, this is usually done by specifying something like "hw:1,0" - somewhere - but I am unable to find this somewhere, well anywhere
So, the audio is played to the default output, together with all other system sounds - not too pleasant when an error dialog pops up at 110 db!

Is it possible? If not, could that become a feature request?

Much appreciated,
Andrej Falout

The easiest option is perhaps to set the USB device as the default audio device in Linux.

http://www.cahilig.org/select-default-a ... ubuntu-804

Alternatively, you can add the following system property when launching Subsonic from subsonic.sh (assuming you're using the standalone version of Subsonic):

Code: Select all

-Djavax.sound.sampled.SourceDataLine=#name_of_audiodevice

I haven't tried this on Linux, but it works on Windows. For instance, I have two devices called "SigmaTel Audio" and "SB Live! 24-bit External". To select the first I would do:

Code: Select all

"-Djavax.sound.sampled.SourceDataLine=#SigmaTel Audio"

Hope this helps!

Thanks for the reply, Sindre!

Setting another card as default is not an option, since that would send all system sounds (like loud error pop-ups sounds) to the same output as music.

I tried "-Djavax.sound.sampled.SourceDataLine=#USB Audio [hw:1,0]"
and "-Djavax.sound.sampled.SourceDataLine=#USB Audio"
but no sound...

Reading http://www.jsresources.org/faq_audio.html did not help either.

I suppose the problem is in device name I'm using, but that seems to me to be correct:

Help? Anyone? Nobody using non-default audio card to play music?

[afalout]

To find out names of audio devices as Java see them, compile and run this program:


import java.io.*;
import javax.sound.sampled.*;

public class audioDevList{
public static void main(String args[]){

//Get and display a list of
// available mixers.

Mixer.Info[] mixerInfo =
AudioSystem.getMixerInfo();
System.out.println("Available mixers:");
for(int cnt = 0; cnt < mixerInfo.length;
cnt++){
System.out.println(mixerInfo[cnt].
getName());
}//end for loop
}
}

On my system, this shows:

polar:/var/subsonic # java audioDevList
Available mixers:
Intel [plughw:0,0]
Intel [plughw:0,1]
Intel [plughw:0,2]
Audio [plughw:1,0]
U0x46d0x991 [plughw:2,0]
Java Sound Audio Engine
Port Intel [hw:0]
Port Audio [hw:1]
Port U0x46d0x991 [hw:2]

Now edit sound.properties in Java installation used to run SubSonic and add:

javax.sound.sampled.Clip=#Audio [plughw:1,0]
javax.sound.sampled.Port=#Port Audio [hw:1]
javax.sound.sampled.SourceDataLine=#Audio [plughw:1,0]
javax.sound.sampled.TargetDataLine=#Audio [plughw:1,0]

In my case, file was: /usr/lib64/jvm/java-1.6.0-sun-1.6.0/jre/lib/sound.properties

That works, but now ALL Java apps on my system output audio to that device - which defeats the purpose of having ONLY music played on that device, avoiding system sounds like incoming mail notifications blowing your ears out at 110 decibels....

Adding -Djavax.sound.sampled.SourceDataLine="#Audio [plughw:1,0]" to java command line does not work in any combination I could think of, with or without other lines I added to sound.properties file.

Does anyone know how to achieve this for SubSonic only, without using system-wide configuration file?

Thanks,
Andrej Falout

Finally, thanks afalout!

For all you non java people (like me) here's the compile steps:

• Copy the above code into a file called 'audioDevList.java'
• javac audioDevList.java
• java audioDevList

I get this output:

Code: Select all

Available mixers:
NVidia [plughw:0,3]
NVidia [plughw:0,7]
NVidia [plughw:0,8]
NVidia [plughw:0,9]
Intel [plughw:1,0]
CX8801 [plughw:2,0]
Port NVidia [hw:0]
Port Intel [hw:1]
Port CX8801 [hw:2]


Now I modify /usr/bin/subsonic (on Ubuntu 10.x), might be subsonic_sh for you. I added the following line. Note the single quotes around the whole line. The # and space require it.

Code: Select all

  '-Djavax.sound.sampled.SourceDataLine=#NVidia [plughw:0,7]' \


'service subsonic restart' et viola!
-m[/code]

Future readers : please add solutions there as they are found

[johngc]

I have tried the above as I am in a similar situation but when I do:

Code: Select all

sudo javac audioDevLisat.java

I get

Code: Select all

audioDevLisat.java:4: class audioDevList is public, should be declared in a file named audioDevList.java
public class audioDevList{
       ^
1 error


I know nothing about java really so have no idea what to do next!

Thanks

[maxslug]

I have tried the above as I am in a similar situation but when I do:

Code: Select all

sudo javac [b]audioDevLisat[/b].java

Spelling counts... the file name has to match the class name.

-m

[johngc]

And that's why you shouldn't try to do everything on your iPad!!

Thank you.

[johngc]

Well the script worked after I *ahem* changed the spelling...

and I get this output:

Code: Select all

Available mixers:
PulseAudio Mixer
NVidia [default]
NVidia [plughw:0,0]
NVidia [plughw:0,1]
NVidia [plughw:0,3]
Port NVidia [hw:0]


I then added the line as directed in my /usr/bin/subsonic file (does it matter where is should be in it?)

but when I restart subsonic, I get:

Code: Select all

* Restarting Subsonic Daemon subsonic
/usr/bin/subsonic: 124: -Djavax.sound.sampled.SourceDataLine=#NVidia [default]: not found

   ...done.


It claims not to find it with every setting , 0,0 0,1 0,3 etc.

Code: Select all

* Restarting Subsonic Daemon subsonic
/usr/bin/subsonic: 124: -Djavax.sound.sampled.SourceDataLine=#NVidia [plughw:0,0]: not found

   ...done.

[maxslug]

I then added the line as directed in my /usr/bin/subsonic file (does it matter where is should be in it?)

Hi John, yes position counts too It's got to be on the extended line that starts the process. the backslash (\) wraps a long line to make it more readable. This line will start with 'java'or '$JAVA' or '${JAVA}'.

Here's a snip of my file for reference :

Code: Select all

${JAVA} -Xmx${SUBSONIC_MAX_MEMORY}m \
  -Dsubsonic.home=${SUBSONIC_HOME} \
  -Dsubsonic.host=${SUBSONIC_HOST} \
  -Dsubsonic.port=${SUBSONIC_PORT} \
  -Dsubsonic.httpsPort=${SUBSONIC_HTTPS_PORT} \
  -Dsubsonic.contextPath=${SUBSONIC_CONTEXT_PATH} \
  -Dsubsonic.defaultMusicFolder=${SUBSONIC_DEFAULT_MUSIC_FOLDER} \
  -Dsubsonic.defaultPodcastFolder=${SUBSONIC_DEFAULT_PODCAST_FOLDER} \
  -Dsubsonic.defaultPlaylistFolder=${SUBSONIC_DEFAULT_PLAYLIST_FOLDER} \
  -Djava.awt.headless=true \
  '-Djavax.sound.sampled.SourceDataLine=#NVidia [plughw:0,7]' \
  -jar subsonic-booter-jar-with-dependencies.jar > ${LOG} 2>&1 &


Make sure there are no spaces after any of the backslashes.

Thank you - all working now

Thank you - all working now

You're welcome. Hopefully Soundcard selection becomes a gui feature for the Jukebox mode.
