I have a Raspberry Pi with a Hifi Berry Mini Amp. But I only connected one speaker to the hifi board. (I build a small radio with it)
Now I'd like to make sure that my speakers play everything. So, f.e. I plugged in the left channel. So now when I play something where only the right channel is used by the audio source, I'd like to hear that.
So basically -> Stereo to Mono conversion. I'd like a software/config only solution. Is that possible?
