I also have a Gigabyte board with HDA audio, and it won't directly play CD sound either. I had already ripped all of my CDs to .ogg files, so I hadn't needed to play the CDs directly. I just tested ripping a small section of a CD using cdparanoia and it does produce a .wav audio file that can be played using sox. I also notice on my computer that mixer doesn't show any controls for CD audio. Unfortunately, I don't remember if CDs worked properly on this computer when I had Linux installed, so I don't know if the problem is FreeBSD or the motherboard. I did find that I have a program called kscd (for KDE) that will play, but I suspect that it uses digital extraction instead of playing from audio. My system uses a Gigabyte GA-MA785GPM-US2H, and the sndstat output is: FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64) Installed devices: pcm0: <HDA ATI RS690/780 HDMI PCM #0 HDMI> (play) pcm1: <HDA Realtek ALC885 PCM #0 Analog> (play/rec) default pcm2: <HDA Realtek ALC885 PCM #1 Analog> (play/rec) pcm3: <HDA Realtek ALC885 PCM #2 Digital> (play/rec) Let me know if you want further information. -- Carl Johnson ca...@peak.org _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
