[Dell Mini 9, Realtek ALC268] Lost sound on Lucid update

Status changed to 'Confirmed' because the bug affects multiple users.

[Jason (jasoncrim55)]

dell mini 9 installed updates on 9/29, restarted, now no audio
all troubleshooting looks normal, sound card recognized, drivers installed, but no audio at all
nothing on speakers, headphones, startup tone

[S (skyssa)]

It has to do with the most recent updates. I formatted my SSD, re-installed Ubuntu 10.04.0 and the audio was fine. Did the slew of most recent updates and now my audio is gone again.

Temp solution:

https://help.ubuntu.com/community/HdaIntelSoundHowto

*After amending alsa-base.conf, make sure you write the added line into the file ("ctrl-O" I think? ...it's listed at the bottom)

After running "sudo alsa force-reload" - restart and everything should be fine. I'd rather an update fix, just in case the next update causes the same problem, but this seems to work for now.

[Daniel Ellis (danellisuk)]

Thanks skyssa! Here is the simple fix for those who have the issue on the Dell Mini 9:-

Edit the file alsa-base.conf by running the following command:-

gksudo gedit /etc/modprobe.d/alsa-base.conf

Add this line to the end of the file, save, and reboot

options snd-hda-intel model=dell

that worked, thanks

The fix worked. Thanks to the people that figured out the problem and the fix.

[dwarf (dpfields)]

I also use a Dell Mini 9 and have lost sound after the last three kernel updates, but this work for me. Should this eliminate the problem for future kernel upgrades?

[Marcus Tomlinson (marcustomlinson)]

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
