Hi Floris, debian user, * Floris <jkfloris@dds.nl> [21. Jan. 2016]:Op Sat, 16 Jan 2016 20:06:22 +0100 schreef Gregor Zattler <telegraph@gmx.net>:since a few days my normal user, which is in group sound, cannot play sound (aplay works but no sound) while root can. Any ideas how to debug this? This is a debian testing system with pulseaudio and mpd running. /dev$ find |xargs ls -ld|grep audio crw-rw----+ 1 root audio 14, 4 Jan 16 16:32 ./audio lrwxrwxrwx 1 root root 8 Jan 16 16:32 ./char/14:4 -> ../audio crw-rw----+ 1 root audio 14, 3 Jan 16 16:32 ./dsp crw-rw----+ 1 root audio 14, 0 Jan 16 16:32 ./mixer crw-rw----+ 1 root audio 14, 16 Jan 16 16:32 ./mixer1 crw-rw----+ 1 root audio 116, 2 Jan 16 16:32 ./snd/controlC0 crw-rw----+ 1 root audio 116, 6 Jan 16 16:32 ./snd/controlC1 crw-rw----+ 1 root audio 116, 5 Jan 16 16:32 ./snd/hwC0D0 crw-rw----+ 1 root audio 116, 10 Jan 16 16:32 ./snd/hwC1D0 crw-rw----+ 1 root audio 116, 4 Jan 16 19:27 ./snd/pcmC0D0c crw-rw----+ 1 root audio 116, 3 Jan 16 19:52 ./snd/pcmC0D0p crw-rw----+ 1 root audio 116, 7 Jan 16 19:52 ./snd/pcmC1D3p crw-rw----+ 1 root audio 116, 8 Jan 16 19:27 ./snd/pcmC1D7p crw-rw----+ 1 root audio 116, 9 Jan 16 19:27 ./snd/pcmC1D8p crw-rw----+ 1 root audio 116, 1 Jan 16 16:32 ./snd/seq crw-rw----+ 1 root audio 116, 33 Jan 16 16:32 ./snd/timerMaybe it sounds odd, but does you have sound when you remove yourself form the audio group? In Debian Testing systemd takes care for setting the right rights That is why you have a "+" at the end of the permissions.Thanks for looking into this. Actually I'm totally unaware of all things systemd. I heard sound when in group audio say two weeks ago. Nonetheless I did a sudo delgroup grfz audio logged in on a VT, played a .wav file with aplay: No sound.What is the outcome of: getfacl /dev/snd/hwC0D0c$ getfacl /dev/snd/hwC0D0 getfacl: Removing leading '/' from absolute path names # file: dev/snd/hwC0D0 # owner: root # group: audio user::rw- user:grfz:rw- group::rw- mask::rw- other::--- Did not know this command but output looks good to me.
You are right, the right permissions are set.
Do you have an .asoundrc file in your home directory?
If you have one remove it.
and try aplay again
If you doesn't have one create one with:
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
and try
aplay -Dpulse foo.wav
success,
