As soon as the card cannot do hardwaremixing, it is blocked
for all other applications. So I personally think it is a bad
design if a single application wants to access the ALSA
device directly and exclusively.
As for the soundservers: If a soundserver grabs the ALSA
device it is blocked. Therefore (in an optimal world) the
soundserver should be the central instance for any audio
application.
Big prob: There still isn't the one and only central
soundserver instance, but havin one would be wonderful in
terms of usability and audio straighforwardness.
