Audio out via HDMI... how?
I have a laptop which has an HDMI output port. I can get video out of that (with xbmc) just fine. Audio, not so much. Like not at all, as far as I can tell. So anyway, here is what I get when I do cat /dev/sndstat: pcm0: HDA Realtek ALC888 PCM #0 Analog (play/rec) default pcm1: HDA Realtek ALC888 PCM #1 Analog (rec) pcm2: HDA Intel Cantiga HDMI PCM #0 HDMI (play) I have the HDMI output wired into my everything-capable Sony 5.1 channel receiver, which then in turn is wired into my 4 (count 'em four) speakers. OK, so now, could somebody please just tell me how I can do a test that will determine why I ain't gettin' no audio? The receiver is capable of decoding 5.1 DTS-HD, Dolby TrueHD, and eveything else too. It is working just fine.. not a thing wrong with it. It works great with my Blu-Ray player and does the digital-analog decoding for anything and everything I throw at it. Again, I just want to know how to _test_ doing some output to that from my laptop, via HDMI. I tried these things, but not a sound was heard: cat /dev/random /dev/dsp cat /dev/random /dev/dsp2 The FreeBSD handbook page that deal with setiing up audio cards doesn't provide a whole lot of guidance for how to test and/or fix digital audio output, whether it is coming out via HDMI (as in my case) or via any other kind of physical transport (e.g. coax or S/PDIF). Somwebody please pass me a clue. I'd really like to get this working. Thanks. P.S. If I have to downmix to 2ch in xbmc before the audio even hits the HDMI cable, I could even live with that. Bu right now, as far as I can tell, I can't get _any_ audio flowing down that cable, period. ___ 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

That made no difference whatsoever to the outcome. There was still no sound coming out when I tried cat'ing /dev/random to either /dev/dsp or to /dev/dsp2. So I'm still stuck. ___ 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
