Whenever I play music (maybe also video, but I’m not sure) I get the left channel through both speakers. I played the same audio file on my computer, and it contains and plays both channels. I tried the cd on my PS3 that is connected to the same tv with the same 2.1 speakers, and it plays both channels. That makes me think it is a pi/OSMC problem.
My pi is connected to the tv through HDMI. I reinstalled OSMC recently and didn’t do any config.txt modifications.
I set the audio device to ALSA, but that didn’t do anything. It’s now back on HDMI.
I set the audio channels to 2.1, but that didn’t do anything, so it’s back to the default 2.0
I set Stereo upmix on, but that didn’t do anything, so I turned it off again.
I set hdmi boost to 5.
I deleted hdmi_force_edid_audio=1 from config.txt
Any suggestions on what I could do to get both left and right audio through the speakers?
Factory resetting my tv solved the issue (at least temporary). With changing the hdmi cable before, I also changed the hdmi input on my tv. It worked temporary, but it changed to dual left channel in some time. Other devices don’t do this. Something with my raspberry pi and OSMC makes my tv set the audio this weird. I changed the topic to unsolved again.
So far, I can’t consistently replicate the issue, and although I’m far from sure, it seems like it only happens when pausing music, turning the tv off, and turning it back on again the next day.
