Sound is not working after upgrading to Ubuntu 9.04 (Jaunty Jackalope)
I had the same problem as a lot of people, actually. I found the following solution to be working for me:
Open the alsa config file by:
sudo gedit /etc/modprobe.d/alsa-base.conf
at the end of the file just paste the following lines:
options snd-pcsp index=-2 options snd slots=snd-hda-intel options snd-hda-intel model=hp-m4 alias snd-card-0 snd-hda-intel options snd-hda-intel enable_msi=1
Solution came from this forum thread. Thanks guys.
I have tried four or five suggestions for editing the alsa database and none of them have worked. In line three of the suggested options, what does model= refer to. I have an HP 6735s which has the Intel HDA sound card from Analog Devices – AD1984A which in the hardware listing calls for the default settings in the .conf file. The default didn’t work and neither has any of the suggested options. No sound in 9.04 or 8.10. Any help would be greatly appreciated.
really helpful thanks a lot
