Subject: [ecasound] Delay with SB Live

It's quite a long time ago, that I mailed about a delay in ecasound,
even with -b:64.
I was suggested to try some other realtime software, to check if it was
ecasound or the OSS sounddriver.
Finally, after a lot of troubles, I've installed the alsa driver.
Now ecasound gives almost no delay with -b:128.
I hope this will be usefull to users of the SB Live card, which also
experiences delay problems.

Hmm, what version of ALSA?
