No sound after update (pulseaudio problem?)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello All,

I'm lost here and I kindy ask for your assistance.
I just made a 'yum update' to update my mythbackend running Fedora 8.
Previously this used to work fine for me, but this time it left me
with no sound in many applications. Whenever I try to play a file with
mplayer, it says: 

==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, s16le, 128.0 kbit/8.33% (ratio: 16000->192000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================
*** PULSEAUDIO: Unable to connect: Connection refused
[AO_ALSA] Playback open error: Connection refused
audio_out: alsa9 and alsa1x modules were removed, use -ao alsa instead.


and if I use '-ao alsa' it starts the playback with no sound at all.

I also noticed my "PulseAudio Volume Control" does not work as well
("Connection failed. Connection refused"). It used to work fine before
the update...


With the update I changed from kernel-2.6.23.15-137.fc8 to
kernel-2.6.24.5-85.fc8. I assume it might be important, although I'm
not sure.


I tried searching the Net but I couldn't find a similar issue.
The strange thing is that I just updated another machine the same way
and it has no problems with sound. It just works there as usual!

I don't know how to trace the problem. I didn't find anything in
/var/log/messages or in dmesg. Are there any specific pulseaudio log
files?
Here's some data I could think of:

# aplay -L
front:CARD=ICH6,DEV=0
    Intel ICH6, Intel ICH6
    Front speakers
surround40:CARD=ICH6,DEV=0
    Intel ICH6, Intel ICH6
    4.0 Surround output to Front and Rear speakers
surround41:CARD=ICH6,DEV=0
    Intel ICH6, Intel ICH6
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=ICH6,DEV=0
    Intel ICH6, Intel ICH6
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=ICH6,DEV=0
    Intel ICH6, Intel ICH6
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
null
    Discard all samples (playback) or generate zero samples (capture)
# aplay -l

I appreciate any ideas!
