some sound engines (like Xine) use them, and others (gstreamer) don't. And I
don't know how to swap them around.
What I did was change the alsa default device depending on whether or not the
USB headset was plugged in. This was done by a udev rule in /etc/udev/rules.d
that named 39-alsa-usb.rules that contained the following two lines:
KERNEL==pcmC[D0-9cp]*, DRIVERS==usb, ACTION==add,
RUN+=/usr/bin/alsa-usb-add
KERNEL==pcmC[D0-9cp]*, DRIVERS==usb, ACTION==remove,
RUN+=/usr/bin/alsa-usb-remove
The scripts /usr/bin/alsa-usb-{add,remove} contained a single line that linked
/etc/asound.conf to one of two prepared asound.conf files:
#!/bin/bash
ln -sf /etc/asound.conf.hw0 /etc/asound.conf
or
#!/bin/bash
ln -sf /etc/asound.conf.hw1 /etc/asound.conf
I can’t find the asound.conf.hw{0,1} files at the moment (I have a non USB
headset now) but they contained a very simple configuration with hw0 as the
default alsa sound device or hw1 as the default alsa sound device in the other
case.
Hope this helps you! :)

(thus Pulseaudio will replace all the other sound servers and layers out there) Try and find a program which pulse cannot handle, either natively or most likely through the alsa-plugin and padsp, the OSS emulator. Admittedly, there are bugs in the alsa-plugin for pulse, but its actively worked on by a paid developer who listens to well-mannered suggestions (not the typical linux fanatic going I don't want anything to be different from 10 years ago when sound on linux was perfect). And no, pulse will not replace all the other sound servers and layers. For pro-audio, JACK reigns, and will do so in the foreseeable future. Pulseaudio is meant for common desktop use, end of. Fortunately, that's exactly where most of us are with regards to sound. I think it bears repetition, for most programs (which don't try to use ALSA in complicated ways) you only need to use pulse's alsa-plugin and it'll work with pulse no problem. Sound APIs such as gstreamer already support direct pulse output.

[arch-general] Bluetooth headphone
Hi, I have a mono bluetooth headphone dongle thing that I got paired using the new KDE4 bluetooth manager (the guys really did a great job on this I might add). I added entries in ~/.asoundrc and can play sound files to it using aplay -D device. Now, how do I get other apps to see it? I dont see it as a device or channel in the mixer? Manne
