the driver is an improved version of OSS audio.c - at least the descriptor parser routine is based on OSS code. it supports generic USB audio class. all audio control units except for graphic equalizers are supported. and the latency is set flexibly up to 1ms according to the application's set up. (this might be too small - i got a bug report that the driver locks up...) 24bit formats are likely not supported yet, but will be fixed soon, perhaps in the next week. please note that it's a tentative version, and thus not included in 2.5 alsa-kernel tree yet but appears only in alsa-driver tarball (atm on cvs only). i'd like to put to the official place once when the driver is confirmed to work fine on most of devices. the question is, which directory should this go to. of course, drivers/usb/class would be the first place. but it might lead to a problem of config dependency. snd-usb-audio requires also some ALSA lowlevel modules as usual like other ALSA modules. i talked with Jaroslav about this, and he think that this is up to the decision by USB guys, too. your opinions? -- Takashi Iwai <[EMAIL PROTECTED]> SuSE GmbH - www.suse.de ALSA Developer ALSA Project - www.alsa-project.org _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
