One of the mpd 0.19.21-1 (Debian Stretch) that I have is playing mono streams on only 1 channel (L). As other mpd instances running on Debian Stretch do not have this problem, I think it must be some ALSA config. There is no /etc/asound.conf and no ~/.asoundrc. I use an external Terratec USB sixfire soundcard. When playing the mono stream with "mplayer" the output is on both channels. This issue is mpd only, but AFAIK not an mpd problem. This is the alsa part of mpd.conf:
Code: Select all
audio_output {
type "alsa"
name "ALSA1"
device "hw:0,0" # optional
mixer_type "hardware" # optional
mixer_device "default" # optional
mixer_control "Master" # optional
mixer_index "0" # optional
}
Anyone a hint why this could happen?
Richard.
