Greetings all, Code: FreeBSD udns 8.3-STABLE FreeBSD 8.3-STABLE #2: Sun May 20 22:25:10 PDT 2012 root@udns:/usr/obj/usr/src/sys/AMD64 amd64 OK. Now that I've got that out of the way, here's my situation: I've got an MSI mobo with an AMD 3 core CPU. The sound is onboard, and is a Realtek ALC892. loader.conf: Code: sound_load="YES" snd_hda_load="YES" I've searched the forums, read the handbook, following all the hints therein. I have 4 stereo output(s) -- front, rear, center subwoofer, & side surround. I have headphones plugged into each of those output(s), Code: # ls /dev/ | grep dsp dsp0.0 dsp0.1 dsp1.0 dsp2.0 but performing the following: Code: cat /dev/random > /dev/dsp0.0 cat /dev/random > /dev/dsp0.1 cat /dev/random > /dev/dsp1.0 cat /dev/random > /dev/dsp2.0 produces no sound! /dev/sndstat: Code: FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64) Installed devices: pcm0: <HDA Realtek ALC892 PCM #0 Analog> (play/rec) default pcm1: <HDA Realtek ALC892 PCM #1 Analog> (play/rec) pcm2: <HDA Realtek ALC892 PCM #2 Digital> (play) --Chris P.S.: Here's all the relevant output.
