The device is recognized: pcm0: at io 0xd400 irq 16 kld snd_cmi (1p/1r/0v channels duplex default) However, whenever the driver is used to play any audio, the system will typcally hang after a few seconds of play. There is no panic message that I can tell (nothing in syslog), and the system is completely unresponsive. The only way to reboot is to reset the system. >How-To-Repeat: # kldload snd_cmi Then use any audio application. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
