[ICH4 - Intel ICH6] pulseaudio no sound in gnome after 10.4 upgrade

Asked by erm67 on 2010-04-01

Binary package hint: pulseaudio

System is a Dell D610 PentiumM 1.87.
After upgrading to 10.4 sound stopped working at all, drivers are correctly loaded, no error messages in dmesg, all levels in alsamixer are set to high and sp/dif output is disabled. I cannot check if sp/dif is working since it is only available through the docking station of my laptop.
Neither the headphones nor the internal speakers work.
Sound works correctly in WindowsXP

After further testing it appears that sound is working on the system but not through pulseaudio

ermanno@ermanno-laptop:~$ aplay -D front /usr/share/sounds/purple/login.wav
Playing WAVE '/usr/share/sounds/purple/login.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo
Sound is played correctly

ermanno@ermanno-laptop:~$ aplay -D pulse /usr/share/sounds/purple/login.wav
Playing WAVE '/usr/share/sounds/purple/login.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo
NO SOUND

@Mark Rijckenberg:Thank you for the guide, I followed it and the problem is now disappeared, don't know what was causing it but at least now everything works again. After step4 I rebooted and voilĂ  sound was working. I can post the logs but I don't think it is useful now.
