Lars (and all) The main problem is that AFMT_FULLDUPLEX appears to be a deprecated device capability flag under newpcm. Rat-4 is designed around full duplex hardware. The previous pcm driver would open (some?all?) half duplex cards with open(.., O_RDWR). Querying the device caps check was the only way to be sure of full duplex capability. I committed a change last weekend that checks whether the driver is pcm or newpcm, and moderates it's behaviour accordingly. I've not had time (or access) to check this with other hardware yet. If you want to play the repository is anonymously accessible: http://www-mice.cs.ucl.ac.uk/multimedia/software/cvsanon.html If you test this and it'd be good to know if this works on other drivers. Alternatively if you have the code for an earlier RAT version you should be able to comment out the AFMT_FULLDUPLEX and AFMT_WEIRD checks in auddev_luigi.c. There's also a minor problem in the way rat attempts to deal with mixer loopback (at least with ES1370). The existing method worked for pcm, but does not for newpcm. I'm not yet sure if this is specific to this card, the way rat talks to the mixer, or it's just a change in the driver interface. The last code I looked at was 4.0-20000703 (newpcm looks great, btw). There look to be some new mixer goodies on the way. Unless someone picks up the gauntlet I'll wait and what happens with the new mixer calls before making changes. Kind Regards - Orion. <39808EEE.894B6DA7@isi.edu>Lars Eggert writes: > I've just compiled rat (from CVS) under FreeBSD-4.1.
