How to force a sound output

[kokurya]

Hi there!
I recently changed my sound setup on my siduction multimedia pc.
Until now it was sending sound and video via hdmi to the TV which worked like a charm.
As I have now a audio set-up which supports S/PDIF i hooked up my Tv via HDMI and my speaker via S/PDIF, which also works.
But with one amazing annoying problem:

• Everytime I start my TV the sound is set back to hdmi-output
• Everytime I stop a video the sound is set back to hdmi-output also

So how can i force the audiosystem to always stick to the S/PDIF output?

Code: [Select]

lspci |grep -i audio
00:1b.0 Audio device: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series High Definition Audio Controller (rev 21)


Code: [Select]

aplay -l

correct setup:

Code: [Select]

pactl list short sinks
8       alsa_output.pci-0000_00_1b.0.iec958-stereo      module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED

automatic fallback when TV is turned on again or after a video was stopped:

Code: [Select]

pactl list short sinks                                             
6       alsa_output.pci-0000_00_1b.0.hdmi-stereo-extra2 module-alsa-card.c      s16le 2ch 44100Hz       RUNNING

Thx & no problem.

I'm pretty sure that i oversee something really simple and stupid...

*edit*
As I don't know which setting did it exactly... Here my "workaround" for now:
I uncommented following lines in  "/etc/pulse/default.pa"

Code: [Select]

### Should be after module-*-restore but before module-*-detect
load-module module-switch-on-port-available
As far as i underestood this is some kind of autoconnect thingy.

Code: [Select]

### Automatically restore the default sink/source when changed by the user
### during runtime
### NOTE: This should be loaded as early as possible so that subsequent modules
### that look up the default sink/source get the right value
load-module module-default-device-restore
Overrides Users wishes...

And I did set a default sink:

Code: [Select]

### Make some devices default
set-default-sink output 4
#set-default-source input

So far it seems to work and maybe this helps some others if they run into the same problem.
