Jim There is a difference in the initialization sequence between 4.6 and 4.7 that might be worth investigating: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/sound/pci/maestro3.c.diff?r1= 1.2.2.11%3ARELENG_4_7&tr1=1.1&r2=1.2.2.7%3ARELENG_4_6&tr2=1.2.2.11 There are additional changes in -CURRENT relating to with suspend/resume which are probably not directly relevant. If you have the stomach for it, I'd recommend grabbing the specs and comparing the ALSA and FBSD versions of the driver. There may be differences in the initialization code that give a clue to what the root of the problem is. Failing this, try polling scottl@freebsd.org who is responsible for the maestro3 driver. YMMV, he's release engineering these days though and could well be busy there since 4.8 code freeze is coming up shortly. - Orion To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
