Although I do find that Pulseaudio - the version as currently packaged in Debian - still has quite some pretty annoying bugs, it is perfectly capable to mix different audio sources. Challenge is that all applications need to support Pulseaudio and/or ALSA is configured to use Pulseaudio by default. AFAIK current Pulseaudio packages for Debian install a system-wide ALSA config file to achieve this. Only thing when you use two users, play music in one X session and then switch to the other session: Then Pulseaudio mutes/stops the first session. If you do not like that, you need to use Pulseaudio in system wide mode - one Pulseaudio running as root - which is not officially supported and currently requires to edit "exit 0" into the start-pulseaudio-kde script everytime it is updated. This could probably be pinned by a dpkg-divert or somesuch however. Other annoying things: - Cannot handle USB sound cards with lots of channels like Sonica Theater. - Sometimes chokes with "usb_set_interface_failed" (lots of messages) and doesn´t detect the sound card at all then. This mostly happens on older not so fast hardware like my ThinkPad T23 Amarok machine here. For that reason I removed Pulseaudio on that machine. So while I can perfectly understand the "apt-get purge pulseaudio" reflex and I did it myself quite some times, I know that Pulseaudio can mix together different audio sources. And it seems to do that at a higher quality than ALSA.
