Well, I just installed Ubuntu 11.04 on a friend's laptop here yesterday, wich also was an Aczer Aspire. So this doesn't seem to be an unknown problem. However, after rebootin twice the sound just came back without any further problems so far... If the same problem occurs with his laptop again and I manage to fix it, I'll let you know (always assuming that the internet here on the camping site let's me login to AskUbuntu again). –  RobinJ Jul 11 '11 at 10:45

My sound system is ATI Technologies Inc RS880 Audio Device [Radeon HD 4200] and I STILL havent been able to get it back. Its installed but isnt recognized –  Jen T-ice Jul 13 '11 at 8:36
Did you try reinstalling or reconfiguring pulseaudio? Try sudo dpkg-reconfigure pulseaudio and reboot. If that doesn't solve it, try sudo apt-get reinstall pulseaudio. –  RobinJ Jul 13 '11 at 9:05

The following instructions for installing the latest ALSA packages via the DKMS .deb installer worked for me on the Acer 5520.


They solved my microphone problems, but they may also save other sounds problems...

Oneiric 11.10

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it is very important to include the essential parts of the answer here, and provide the link for reference. This prevents linkrot and old documentation from creeping in. –  Jjed Dec 3 '11 at 20:45
