HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

[bartman2589]

Might be about time to update this since PulseAudio is used by default now in Kubuntu 10.10 (which really really sucks since the default configuration provides NO access to all of the input channels of the sound hardware used, making it impossible to configure various things like Mic 2 selection, Mic boost, mute or unmute aux/line in/phone or any other input).

Thank you for this.

As you know, Pulse audio defaults to two channels.

Why ?

Almost all mainboards these days comes with at least 6 channel integrated audio.

But because pulse audio defaults to 2 channels people can't enjoy surround sound (without doing some serious tweaking) despite having the hardware.

I had this issue on my Dell XPS M1530. I resolved it by following the instructions in Appendix A point 1 above.

My specific actions were as follows:
rm -rf ~./pulse
sudo reboot 0


RESOLVED
I have commented on this so people searching for this issue on Dell XPS M1530 will find help

/usr/bin/pulseaudio-equalizer: line 78: 10+: syntax error: operand expected (error token is "+")

This happened after reinstalling (completely removing with synaptic and installing again).
Any ideas?

EDIT: deleted .pulse in home folder and works now

I was wrong about editing preset file to add custom frequencies.
This being, PLEASE tell us how we can add them.

I am having some issues. I can hear sound fine but when I open up the Pulse VolumeManager the vu-meter isn't registering anything for the ALSA plugin. When I make a loopback adapter and try using that instead I still don't get anything. I tried to record the monitor but no audio was recorded. This seems to work fine for the internal mic, just not from the soundcard itself.
