10.10 no sound hda-intel realtek 888 acer aspire 7736z

[Matthew Hudson]

On upgrade to 10.10, I completely lost sound. This happened with 10.04 as well, but at that time there were newer ALSA drivers that mostly fixed the problem. This time, the drivers seem to already be the newest, but still no sound. I've used Synaptic to try to reinstall all my sound components, but they all seem up to date.

Help?

Maybe my alsa-info output helps?

I have the same problem on an Acer Aspire 7736ZG after updating to Ubuntu 10.10 (amd64).

[Matthew Hudson (matthewlhudson)]

I have also verified that this bug exists when using a "clean" copy on a USB stick. No sound.

This bug report might be a duplicate of bug #617647.
