Omxplayer supports 5.1 surround?

Omxplayer supports 5.1 surround? (with an USB soundcard, of course).

[rpdom]

AFAIK omxplayer only supports the native audio interfaces on the Pi - that is the HDMI and the A/V jack socket. Unless something has changed it doesn't support any other audio devices, including USB ones.

Newer versions of omxplayer support ALSA and even PulseAudio via PulseAudios ALSA compatibility layer.
That means that omxplayer does support sound over Bluetooth indirectly too.

Ok cool, I sit corrected

If your TV / sound system connected to HDMI supports AC3 / DTS decoding you can use the "-p" or "--passthrough" option.
tvservice -a
will tell you if it is supported.

With omxplayer, using the option of -o alsa like "omxplayer -o alsa bubles2.wav", is able to send sound through the USB soundcard to the speakers. But the question is if it supports 5.1 surround, because all the 5.1 audio I send through it is downmixed to stereo.

Code: Select all

omxplayer -o alsa bubles2.wav
Audio codec pcm_s24le channels 6 samplerate 44100 bitspersample 24
Subtitle count: 0, state: off, index: 1, delay: 0

The same file, with mplayer, uses the speakers correctly in 5.1

Code: Select all

mplayer --channels=6 bubles2.wav

You could try the
--layout 5.1
option.

Interesting. With that option --layout 5.1, the audio file is not downmixed to stereo. The front right and front left speakers play their channel, but the other 4 speakers dont play anything.

From where does omxplayer pick the configuration when doing the -alsa thing?

I guess you looked up in google and discovered my footprints

No, I went directly to the issues.
