No digital audio from new notebook

Just got myself a new Acer Aspire 6935G notebook. Amazing unit with everything I need and it works almost flawlessly. I’ve tried hooking the unit up to my tv and home theater system and the picture through the hdmi cable is incredible, however, i acnnot seem to get sound from the optical (spdif) output from the notebook. Sound is on-board Realtek high definition audio. Any idea’s what I might be able to try?

Thanx in advance

I have the same problem with my Dell Studio 15 laptop. When I hook up the HDMI it provides video, but no audio. I would have written a bug report, but I do not have easy access to the TV for the HDMI hookup/test, and I know from experience that the alsa/openSUSE developers need a lot of iterative input in order to solve such problems, and I can not provide that for HDMI.

As best I could, I thoroughly checked my laptops configuration (via install apps, diagnostic scripts, mixer settings, etc …).

I did watch a thread on IRC freenode channel #alsa where one of the guru’s there helped an HP user (DV5) get their HDMI working (both audio/video) so I know its possible for some laptops with alsa. You could install a program like “xchat” and log on to freenode IRC channel #alsa and see if you can get help there.

In the mean time, for what its worth (which may not be much given my own failure) we can take a loot at your settings. If you wish to try, then assuming you have openSUSE-11.1, please in a terminal with root permissions, run the following twice:
the first time to update the script and the second time for the script to diagnose your pcs audio hardware/software and upload the config to the internet. It will give you an internet URL where that info is posted. Please post here the URL. JUST the URL.

Please also run the following in a terminal and post here the output:
rpm -qa | grep alsa
rpm -qa | grep pulse
rpm -q libasound2
uname -a
cat /etc/modprobe.d/sound

That information should reasonably define your PC’s hardware/software setup, and possibly something incorrect can be spotted. Again, no promises, as I don’t have this functioning on my laptop.

It’s actually NOT the HDMI that I am trying to get sound out of…it’s the SPDIF Optical output. Don’t know if that makes a difference…

I also don’t have hdmi sound output. I post the info that oldcpu requested. Is it enough to have someone helping me?

Best regards
