ESD couldn't possibly help you because it's OSS based. However, the
latest alsa releases support something called dmix by default. This is
alsa's software mixer, and I've had good success playing multiple sound
sources using it.
BTW: I have also used it with yasr, and it shuts up quite quickly. Of
course, this is using alsa's oss emmulator, so only one sound source
(yasr) at a time because of the oss restriction.
So, Mike, can we look forward to an alsa native yasr sometime soon? Have
I intrigued you yet?
PS: You don't say what wireless device you have in your Thinkpad. My
current Thinkpad is an X31 model with a IPW2100 wireless device builtin.
It works perfectly well with Linux, but I had to get the binary (non
open source) drivers and install them in /lib/firmware first. The issue
is that our GPL supportive distros like Fedora and Debian aren't going
to ship binary drivers. Nor would I want them to.
