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

Rebooted

Solution #2: Didn't work

sudo alsa force-reload

Reboot

Solution #3: Didn't work

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload

Reboot

Solution #5: Didn't work and my NIC and mouse stopped working

sudo apt-get install linux-image-3.8.0-19-generic

Reboot

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.

pulseaudio --check

returns nothing

pulseaudio --dump-conf

  • Welcome to Ask Ubuntu! Could you edit your question and provide more details? Like the Sound Card you are using? The output of pulseaudio --check, pulseaudio --dump-conf, amixer -c 0, pacmd dump-volumes and pactl.

  • I have this same issue. For me, sudo alsa force-reload works untill the next reboot. Is this what you mean under 'Solution #2'? Aug 21, 2013 at 9:56
  • No, for me none of the solutions I have tried so far have worked at all.
