Hi, snd-usb-audio is a bit updated. i borrowed a usb microphone and found that there was a deadlock at exit of capture. now it's fixed. the source codes have more comments and readable (hopefully).
most of debug messages have been moved to snd_printdd(). that is, to show such debug messages, you'll need to configure alsa-driver with --with-debug=detect. if your usb device doesn't work try this, and send me the output of kernel messages together with the output of lsusb. the co-existence problem with oss audio module can be fixed by adding an entry to /etc/hotplug/blacklist. the file would be dependent on the distribution, though. 18/20/24bit formats are not supported yet (if 3-byte format). so far, i have no plan to port the usb midi driver for alsa, since there is already a usb midi daemon (see alsa-devel archive). not like an audio device, the access timing to a midi device is not so critical. in the case of audio device, we have to send continuous packets at each 1ms, sometimes even with a sync pipe. unfortunately, this is fairly difficult to be implemented on the current framework of usbdevfs. on the contrary, midi can be relatively easily done on usbdevfs. however, i'm not sure about the latency over usbdevfs. if the latency is too bad, i have to change my mind... btw, from tomorrow i'll be at LinuxTag at Karlsruhe. answers will be delayed until the next week. ciao, Takashi _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
