upgraded to ubuntu 8.04 dev., lost sound

I've lost sound after the update....I have sound settings set to autodetect, I've tried Alsa and Pulse audio but no bananas

Anyone have a clue? It seems all the plugins are installed...sound worked outta the box with gutsy....I have a realtek HD card.

thanks

 

Audio jacks work?

 

Yes, they work...I'm missing a plugin or have a setting wrong somewhere I think....can't figure it out

 

I know that's the problem I had when I installed 7.10, and I had to fix it by adding support for my card to some list or other.....maybe it's something similar.

I did this command:

and then added this to the end of the file:

 

thanks pixelot....I'll keep that in my bag of tricks next time I go into Ubuntu....gonna check Ubuntu forums now also...

 

This will only work if you have a SigmaTel sound chip.

Reaktek isn't in that model line.

 

I would recommend downloading and building the latest ALSA from www.alsa-project.org

 

I wasn't suggesting that those exact steps would work for him, just that it might be something similar.

 

wait for April to come

8.04 is still in develpment so the best thing to do is just wait if you have problems (imo)

 

yes, april isn't far off

 

yeah, definitely wait for april to come around, though i would also recommend liquidiq's info above about compiling alsa drivers from source to see if that will help (after uninstalling alsa from ubuntu first of course). many people with similar problems saw their issues fixed my doing this, so it's worth a shot.

 

Well, I upgraded to 8.04, but I didn't lose my sound. In my situation, it's loud and crackly. I have an HP Pavillion dv6000. Also, the sound buttons on my keyboard do not change the level of sound like it should. Any suggestions on ways to fix it? Thanks!

 

I know this thread is about the dev version but I had the same problem with the 8.04 release and I just found the solution for my audio problem here. I hope this might be helpful to others.
