Ubuntu 8.10 - No sound - Realtek ALC655 chip

[Simon Ward]

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 i386 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

I also added:

updated:

and rebooted, but still nothing.
