I upgraded to 13.04 and afterwards the sound wasn’t working. When I look in the sound applet the only device listed is Dummy Output. I have looked online and I tried a couple solutions with no luck. I believe my sound card is being detected by the kernel but it isn't being used.
lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: AOPEN Inc. Device 0501 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d8200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 03) (prog-if 00 [Normal decode])
Here are the solutions I have tried:
Solution #1: Didn't work
sudo gedit /etc/default/speech-dispatcher
Changed RUN=yes to RUN=no
Solution #2: Didn't work
sudo alsa force-reload
Solution #3: Didn't work
sudo apt-get remove --purge alsa-base pulseaudio sudo apt-get install alsa-base pulseaudio sudo alsa force-reload
Solution #5: Didn't work and my NIC and mouse stopped working
sudo apt-get install linux-image-3.8.0-19-generic
Solution #6: Appears to work
I had version 3.2.0-51 of the kernel installed from when I ran 12.04, the last time the sound worked, so I rebooted and use grub to selected this version, Now my sound works and the NIC and mouse still work.
Additional Info: My sound card is an on-board sound card, so the motherboard is an Aopen i915Pa-E R1.00.
