To date the sound card has worked fine playing ogg

However, where it seems to struggle is with programs like Skype and Openwengo,
two VOIP applications. I believe it has something to do with operating in
full duplex ie it can't record and play at the same time (I don't have
Windows to test this theory) and/or the state of Alsa support for the card is
such hardware mixing (which I don't think the card supports) is the only
viable option for using these programs
Cards that do hardware mixing (when supported by the driver) makes life much
easier. I have a similar problem with skype, although the problem is
that skype uses the older OSS (/dev/dsp) sound API instead of ALSA,
so you can't have alsa apps and skype using the sound card at the same
time (unless there is hardware mixing, which allows multiple apps to
open the device at the same time).
Under recent ubuntu releases (and presumably other distros), multiple
ALSA apps can use the soundcard at the same time with software mixing.
(This is what esd tries to do, except it doesn't work with non-esd
The SB Live is/was a good card under linux for hardware mixing, although
I don't know if they're still sold anymore.
