Greetings,
I am new to this list. I have a computer with these:
---------cpu-amd64-2 cores, dsp: HDA NVidia/Realtek ALC662 rev1
---------o/s cblfs-linux 64-bit kernel-2.6.35.4, xorg-7.5 kde-4.4.5, udev-147
---------audio-progs: alsa-1.0.23. pulse-0.9.21 (default configurations in
/etc/pulse)
--------my /etc/asound.conf file has these:-
==================================================
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}
--------my udev-rule for alsa looks like this:-
==================================================
# Give the audio group ownership of sound devices
SUBSYSTEM=="sound", GROUP="audio"
SUBSYSTEM=="snd", GROUP="audio"
# ALSA Devices
# When a sound device is detected, restore the volume settings
KERNEL=="controlC[0-9]*", NAME="snd/%k", ACTION=="add",
RUN+="/usr/sbin/alsactl restore %n"
# Sound devices
KERNEL=="admmidi*", GROUP="audio"
KERNEL=="adsp*", GROUP="audio"
KERNEL=="aload*", GROUP="audio"
KERNEL=="amidi*", GROUP="audio"
KERNEL=="amixer*", GROUP="audio"
KERNEL=="audio*", GROUP="audio"
KERNEL=="dmfm*", GROUP="audio"
KERNEL=="dmmidi*", GROUP="audio"
KERNEL=="dsp*", GROUP="audio"
KERNEL=="midi*", GROUP="audio"
KERNEL=="mixer*", GROUP="audio"
KERNEL=="music", GROUP="audio"
KERNEL=="sequencer*", GROUP="audio"
KERNEL=="by-path/*", GROUP="audio"
==================================================
--------sound devices in /dev appear as:-

a) I am using system5 init and alsamixer refuses to start on the CLI at run-
level 3 reporting
"pulseaaudio' connection refused (or somesuch) but...
b) alsamixer starts after login in kde in konsole; sound devices are
correctly reported (on the cli); aplay reports no errors but no sound is
heard and outputs are not mute.
b) Still in kde, When the ownership/permissions on /usr/lib/dbus-1.0/dbus-
daemon-launch-helper
file are set as shown above the KDE System Settings/Multimedia dialog
reports a dummy device
I am wondering if the failure to start alsamixer and aplay before kde
starts indicates that consolekit and hal are
disabling the functioning of the setup.
Advice on all the above/to have the sound devices
recognised and functional in KDE-4.4.5 would be much appreciated.
sincerely
sibuXolo
