Hi All,

So I'm trying to setup a new HTPC, but can't get pulse configured properly, so there is no sound. I'm pretty sure it's not a driver thing as I've isolated the output device I want to use (onboard HDMI on an ASRock Z68M-ITX/HT), and have tested it fine from the CLI:

# aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Left.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

No matter what input/output combo I choose in the sound preferences though, I get nothing. I've also tried manually editing with no luck.

Any ideas? Thanks muchly...

Random thoughts...

Try re-running the "aplay" command w/ "-D pulse".

If that doesn't work, then you might want to verify that the pulse plugin for alsa is installed and configured:

Verify that /etc/asound.conf contains something like:

@hooks [
    func load
    files [
    errors false


If it does, then verify that /etc/alsa/pulse-default.conf exists.

The point of the above steps are to make sure things are configured for those apps using alsa directly, but on a system configured to run pulse.

So..., if there's still no sound, you might try playing around w/ "pacmd". Simply type "pacmd" at the CLI and you'll be in the pulse "shell".

Use the "list-sinks" command to get the list of possible places to direct sound.

Once you've located the likely device, enter a command that looks like "set-default-sink alsaoutput.pci-000000_06.1.analog-stereo"..., with the device name adjusted accordingly.

The upshot of all this is to verify that ALSA provides an interface to Pulse (for "backwards" compatibility), and that Pulse is configured to use the appropriate ALSA driver/device.

HTH and apologies beforehand if you've tried all this already...

Looks like noone knows the answer here. Consider asking in the PulseAudio list
