[Alpha] usb sound cards support for raspbmc

[s7mx1]

There is a udev script that should (software) unmute sound card/speakers for you. It's not possible for me to test it for all the sound cards therefore that's one place to look at.

However your case more looks like the right xbmc was not running. Double check .xbmc-current is linked to the right xbmc.

Code:

ls -lrta ~/.xbmc-current

if its pointing to the right location then make sure xbmc is stopped then start it

Code:

sudo initctl stop xbmc
sudo initctl start xbmc

Cambridge DacMagic works nicely off laptop running ubuntu 12.04.
It also seems to get detected on the Raspi, pactl gets me the output below.

s7mx1, you mentioned to harmenzon that sound card might be muted, since it has no mute function in itself, and it works off another computer, would the muting be in the software somewhere, and if so, how do control it?

That is quite understandable ;-)

That gives me the following output, but I cannot determine if that is the right xbmc, though. Stopping and starting xbmc does not make a difference.

Excellent! Thanks

I've got the same issues as Sir Gallivant.

Same DAC and same results. I can see the additional settings under Settings --> Music So that makes me think that the link is to the correct version.

[s7mx1]

It's the wrong one. Did you follow the instructions as user pi ?

You could try the following to see how it goes

Code:

cd ~/
rm .xbmc-current
ln -s /home/pi/.upgrade/xbmc-rbp-pulseaudio-20120706/xbmc-bcm .xbmc-current

restart xbmc afterwards

The DAC should be fine. I need you to run the following commands as user pi and post back the output

Code:

pactl list sinks
pactl list short clients
ls -lrta ~/.xbmc-current
ps -ef | grep xbmc

As far as I can be sure, yes I did. I will stop for tonight, though, and go through all steps again tomorrow, from scratch, and double-check each step. So far thanks a lot for your help, let's see if a bit of rest will make a change.

Your last idea did make a change, however, the xbmc reacts a lot faster and smoother, but now I am unable to get the music add-on working, no music is being played.

Code:

pi@raspbmc:~$ ls -lrta ~/.xbmc-current

I've just gone back and looked over pulseaudio again

I changed /etc/pulse/default.pa
load-module module-cork-music-on-phone
to
load-module module-role-cork

and
load-module module-detect
to
load-module module-udev-detect

untarred the modded xbmc, removed the .xbmc-current and relinked.

All is now up and running nicely.

[s7mx1]

my pulseaudio does not use default.pa as it runs in system mode (system.pa). Re-link the .xbmc-current did the trick.

That works, thanks.

Still need to get the add-ons working, though, and for some reason I am unable to get the xbmc remote app for android to hook up.

any update? I'm really longing for using this! Anything we can help with?
