The day will come soon when there will be no audio cards on the market compatible with the old driver and we'll have solved the problem :) (the GusPnP is already out of production, and CreativeLabs seem to have moved to the Vibra16X codec and this seems to be unable to do full duplex (to best of my knowledge, even the commercial OSS cannot do that). > drivers and Luigi's driver hasn't got that support, nor is it in > his plans AFAIK ... Speaking of mmapped stuff, it is not that hard to add support for it (i'd say 80% of the code is already there, including the basic mmap calls; one only needs to play with syncronization information). Support for it will come when we find someone who understands what the mmap code should do (i suspect it resembles the microsoft audio api), and has code to test the thing. I am more than willing to help with the details, but no volunteers shows up... cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
