Hi there.
thanks for mpd!
i have mpd outputing audio to jack.
audio_output {
type "jack"
name "My JACK Device"
}
and i use an alsa output just to remote control a mixer.
audio_output {
type "alsa"
name "My ALSA Mixer"
device "none" # <=
mixer_device "hw:1"
mixer_control "Master"
}
this is working perfectly, as intended. however, mpd actually tries to
use alsa for output as well. and complains a lot, spamming the log file.
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM none
Jan 23 21:31 : alsa_output: Failed to open "My ALSA Device" [alsa]: Failed to
open ALSA device "none": No such file or directory
it would be nice to have some way to disable this. see below for the simplest
patch i can think of.
cheers
felix
