Linux (Subject changed)Eden upgrade broke Dolby capability on Acer Revo R3610/Ubuntu 10.10?

sudo apt-get remove pulseaudio
Reboot the revo
Load XBMC and then you will get sound.

I revisited this thread tonight because my sound stopped working AGAIN after a Linux kernal update (Dolby had somehow got switched back on, and I have no idea how)… grrrr… anyway, I don't advise doing what is suggested here because of this:

I bolded the "ubuntu-desktop" part because I suspect that most users would NOT want that removed, and you might miss it if you only take a quick glance at what's being removed!

I've got a similar hardware as yours except I've got the Revo 3700 and an Onkyo reciever using HDMI and when my sytem first upgraded to Eden I had no problems at all. Then I got to reading about the new Audio Engine and wanted to try and get blu-ray images to play and managed to mess my installation up to the point I decided to just backup my userdata folder and start over with a fresh eden install. Once that was done I noticed my audio options had changed in XBMC, previously I was using a custom plug nvidia setting and everything was working perfect and after the clean install custom plug was no longer and option, in fact my audio options were very limited for some reason, only having a DTS and AAC capable reciever option whereas previously I had more options available plus the ability to define a custom plug. I decided at this point it probably couldn't hurt to try one of the nightly releases and so I did that and suddenly had more audio options available than ever before, however it still seems to be missing the ability to define a custom plug or maybe i'm missing something but it doesn't really matter as I did eventually get the sound working once again on movies and music but lost the menu sounds when navigating through XBMC although they will play if I am watching a movie and bring up the menu I get menu sounds but once I stop the movie the menu sounds disappear. I'm not at home now where I can check but once I am I will post back and let you know what my current settings are and you can see if they will work for you.

The thing that really gets me though is that even after upgrading to eden 11.0 everything was working perfect, I truly considered it a perfect installation with working menu sounds as well as perfect playback of 1080p mkv's. I still had my previous audio settings using custom plug until I did a clean install and then my problems began. I originally was using a version of XBMC live that I downloaded over a year ago that seemed to have some kind of bug in which the grub menu would not load and so I had lost the ability to go into windows 7 and after several attempts and formatting both windows and linux and ending up with the same results I finally settled on not using my windows 7 on the acer and it simply booted directly into XBMC, since then I've had XBMC running perfect and updating my system via Webmin. Now I once again have access to my windows 7 via the grub menu so at least that is a plus to doing the clean installation.

Here's a screenshot of my Audio settings and as you might notice I don't have AC3 or DTS checked but that's only because I have some unusual needs with my setup, plus I'm still experimenting with everything but so far everything is working as it should on the video's I've tried out things such as avi's mkv's and iso's with no audio problems.
