Cannot Switch Audio to HDMI
 
Hello everyone and thank you for taking the time to read this thread. I installed Debian Wheezy on my computer about a month ago, and I must say, I am impressed with how well it set up my hardware. I have one annoying problem though. I cannot get any sound to play through HDMI. I can get sound through the audio jack on the front of the computer, but not through the HDMI cable that extends from my NVIDIA GeForce GTX 560 Ti to my monitor for both video and audio. Pulse Audio appears to recognize my HDMI cable as audio capable. Here's the output from PACMD list-sinks
Code:

If I load alsa-mixer and select HDA video, I get options to either mute or unmute S/PDIF, S/PDIF1, S/PDIF2, and S/PDIF3, but no volume bar. Anyone have any suggestions?

I'm not sure if this will be helpful but I have an AMD video card and the HDMI audio is disabled by default. To get it to work, I had to append "radeon.audo=1" to the kernel line of my mkinitcpio.conf file (this starts the service at boot up)

Hi,

I had problem that presented itself exactly as you describe. I found that I could only get pulse audio to send the output to hdmi sink if process producing the audio was started after the hdmi cable is connected. Eg make sure you the process is not visible in the "Playback" tab of pavucontrol when you connect the hdmi cable.

HTH,

Evo2.

Thank you for your confirmation evo2. I have done some more research, and I have been able to get my audio working using speaker-test -c 2 -r 48000 -t sine -D hw:1,7. ALSA has (or had?) an "Under-Enumeration of Logical Devices" problem where it only detects the first audio device. To fix this, I added a line to my /etc/pulse/default.pa as follows: load-module module-alsa-sink device=hw:1,7. Now, I can hear audio in KMix when I go into settings->audio setup, and select the appropriate audio device. Wooo hoooo, progress! However, I cannot hear audio anywhere else on my system. I cannot hear audio on KDE boot or playing a movie or at any other time. When KDE starts it gives me a message saying that my headphone jack (Built-in Audio Analog Sterio) has a higher priority, and that it switched to that device. I have set the priority of my new device to highest in the sound configuration menus. Does anyone know what this new problem could be?

Okay, so I finally got KDE to use HDMI. Apparently, pulse restores the default audio devices everytime the computer is rebooted. Also, KDE seems incapable of switch audio devices after it's started. As a result, everytime I rebooted the computer my audio devices were changed back to the incorrect settings. To fix this, all one needs to do is delete the *stream-volumes.db file under ~/.pulse. This will cause KDE to actually use your preferences.
