[kreator71]

Hi, all.

I need help. RUNEAudio ( 0.4) installed on RPi 3. Raspberry plugged from USB to USB input of AV RECIEVER Harman Kardon AVR 445. Music playing but sound is mono in both of speakers. From HDMI to TV Samsung everything OK. Sound is stereo. What I can change for normal sound playing from USB in this installation.

Sorry fo my english (learn i school 20 years ago)))))))

Hi kreator71,

your DAC seems to be a 5+1 channel device, right?

I think mpd uses the wrong channels to play the music.
To find this out you have to check / post your debug data (like mentioned on the post a reply page).

Hi Frank. Thanks for answer.

Only two channels available on AV reciever from USB (i tried 5.1 from LibreElec, not available). At the same time, debugging mode on RuneAudio show all 5 channels.
