Public bug reported:
Hi, this is my first bug report, so apologies for any mistakes.
Following an update prompted by the icon in the top right corner of
Gnome, I no longer have any sound, including login. The hardware works
fine in Windows XP.
My desktop is dual boot (XP and 8.10)
I'm using Ubuntu 8.10 Desktop,
Kernel version is 2.6.27-9-generic,
Onboard sound card is a Realtek ALC655 chip.
Nothing is set to mute/zero, including in alsamixer ( alsamixer -Dhw ).
If I go System>Preferences>Sound and select SiS SI7012 with ALC655 SiS
SI7012 (ALSA)
I get the following:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink:
Could not open audio device for playback.
When set to Autodetect, it 'plays', but I hear nothing.
SiS SI7012 with ALC655 SiS SI7012 (OSS) > Test = 'plays', but I hear nothing.
PulseAudio Sound Server > Test = 'plays' but I hear nothing.
OSS - Open Sound System > Test = 'plays', but I hear nothing.
ALSA - Advanced Linux Sound Architecture > Test = 'plays', but I hear nothing.
I tried:
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils
linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2 and
then rebooted.
This made no difference at all.
cat /proc/asound/cards
shows:
0 [SI7012 ]: ICH - SiS SI7012
SiS SI7012 with ALC655 at irq 18
