Hi!

I^m trying to get my Asus u7 (usb soundcard) to work under openpli.

I have build a new core with the correct correct linux kernel modules (eg. snd-usb-audio) with it. I have managed to make the soundcard work under ALSA, but when i see TV or use Mediaplayer the sound goes out from the hdmi instead :\

 

How do i make Gstreamer to choose the audio to alsa?

 

I actually only need this for mediaplayer to play Dolby TrueHD and DTS-HD Master Audio. Because i don´t have a hdmi A/V-reciver.

gstreamer is not involved in TV or movie playback.

Then how does the sound go through hdmi when alsa has no soundcard? And how do i change so i use alsa instead?

 

I can´t really understand how the sound works at all on these systems

Non-DVB media (mp4, mkv etc.) is player through gstreamer. DVB media (mpeg transport streams -> recordings) are played in hardware. You can never re-route that to alsa.

So then it´s possible to re-route the sound from gstreamer when i play .mvk from mediaplayer plugin ... (i think that it uses gstreamer)

Is it the gstreamer alsa-sink i have to use to make the magic happen?

Yes, that should be possible, to make gstreamer use the alsa sink instead. Exactly how you're going to have to find out yourself But note that A/V sync will probably be (far) off.
