Pulseaudio

Hi, I'm been testing different settings in pulseaudio. I wanted to disable upmixing from stereo to 4.1 as my amplifier does this. I also been investigating how the LFE channel works. I only have two stereo cables from my soundcard (meaning 4channels). So I wanted to route all bass to front-speakers, as my amplifier then automatically sends it to the subwoofer (at least it seems so).

I didn't succeed with what I wanted, but I did learn some things about pulseaudio. And got my audio to work pretty good, even if not exactly as I wanted. Now my system does remix audio from stereo to 4 channels (front-left,front-right,rear-left,rear-right). But the reason why this is enabled is that it also routes the center channel to front speakers.

Here's a summary of stuff that I want to remember next time I work with pulseaudio:

• pavumeter:
• paman:
• /etc/pulse/daemon.conf: ... remix, channels (example)
• /etc/pulse/client.conf: ...autospawn...
• /etc/pulse/default.pa: ... sink, remap
• pulseaudio -k && pulseaudio --start

For now I just write keywords. And soon I'll expand these keyword into something useful for more people then me :)
