Here is the solution for the bugs above, I tried it on mine, Ubuntu 9.04 it works.
1. Type the following command into the Terminal. (Applications -> Accessories -> Terminal) gedit /etc/modprobe.d/alsa-base.conf 2. Add these lines to the end of the file: # Keep snd-pcsp from being loaded as first soundcard options snd-pcsp index=-2 alias snd-card-0 snd-hda-intel alias sound-slot-0 snd-hda-intel options snd-hda-intel model=dell-m4-1 options snd-hda-intel enable_msi=1 3. Navigate to System -> Preferences -> Sound and change everything to ALSA Ubuntu Sound Preferences 4. Go back to your Terminal and type in this vim /etc/group 5. Replace the following line: (or something very similar to it) audio:x:29:pulse with this audio:x:29:<your Ubuntu login name>,pulse 6. Reboot and test your sound. :) For more detail please check here: http://idavespot.com/laptop/ubuntu-904-no-sound-on-hp-compaq-cq40/ -- Hp-compaq notebook,no sound in ubuntu 9.04 https://bugs.launchpad.net/bugs/360137 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
