However for the 505H? they changed the sound chip from NeoMagic to Yamaha (should be better, but no driver :-(. I can get Yamaha datasheets for YMF724 and YMF754 from their website but the chip in the Sony id's as 1073-0010 and the two datasheets I have id as 1073-000d and 1073-0012. Haven't yet looked at how different they are. (I presume I have a 744 or such; no datasheets are found on Yamaha's website (bad links; a search does show pointers to the pdf directory but the files aren't there). I wondered about how easy a driver (for just play/record for now; midi would be nice and I don't know all that /dev/dsp can do) would be for the pcm framework, given these datasheets (presuming that they are enough like the chip I have)? I have done some kernel hacking but it would be nice to start with a working driver for something... (or is someone planning this or something like it anyhow?) -- Pete To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
