SOLVED No sound (mostly) via HDMI

[cristjc]

I decided after installing my second Sapphire Radeon 4850 and crossfiring them that I would go to HDMI output for both the video and audio as the video cards have HD audio support. Bought a HDMI cable and connected it to the newer 4850 ( that has an HDMI connector ) ran it into my Viewsonic 24" LCD, pulled my Soundblaster Audigy card out and connected my 2.1 speakers to the audio out on the monitor. Sound works fine on the occasional times that I boot to Vista-64 bit, but under Kubuntu Jaunty, not so good. On KDE startup and shutdown I get about the last 1/3 of the sound file to play. Under Amarok, I can play back .ogg rips that I have. Other than that, I get no sound at all. Games, flashplayer, nothing...

Is the issue that I have 2 of these cards installed? I am at a loss as to what I need to look at next...

Re: No sound (mostly) via HDMI

The most important thing is to open System Settings -> Multimedia and check for the audio devices that you see. Does anyone look like HDMI? If so, you'll need to move it to the top. You can make changes and test in real time see if you get the sound right ...

Re: SOLVED No sound (mostly) via HDMI

What I ended up having to do is install pulse and edit my /etc/modprobe.d/alsa-base.conf and add

options snd-hda-intel bdl_pos_adj=64
options snd slots=snd-hda-intel
# moNa.h2kiZ7VIR82:Sapphire HD 4850 1GB GDDR3 PCI-E Dual Slot Fansink
alias snd-card-0 snd-hda-intel

As well as edit my etc/pulse/default.pa
load-module module-alsa-sink device=hw:0,3
