Re: [Freevo-users] mplayer, hdmi, ac3, tv, surround amp = digital noise?
Hi, did you try to output dts/ac3 encoded audio through HDMI instead of raw PCM? mplayer -ac hwac3,hwdts -ao alsa:device=hw=0.3 master_and_commander.iso -- strawks On 18/11/2009 13:24, Stephen Rowles wrote: > Hi all, > > Not really the right place, but before I subscribe to alsa / mplayer to > try and work out what was wrong I thought I would start here :) > > I've got an ASRock ION-330, and I'm trying to get surround sound sorted > out.

Re: [Freevo-users] HDMI output with audio in Linux?

I have a laptop with an NVidia 8600M/HDMI output and audio works through HDMI, but I have only stereo output, no 5.1 (but maybe it's possible), using nvidia binary driver (I don't know if it works with the nv driver). I think all nvidia cards with an HDMI out will work (at least with the binary driver) although you should check before buying. I also have a Gigabyte with an intel G45 (GMA X4500HD) with an integrated HDMI out. When I was testing sound through HDMI was not available but from what I've read sound should now work since alsa 1.0.18 (but I didn't try it since I use an optical SPDIF cable). - From what I know it should also work on ATI cards. Anyway you should check on alsa website : http://alsa-project.org/main/index.php/Special:Search?search=hdmi&go=Go - -- regards, strawks -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmbFUMACgkQ+2TXLlA5m79vIACcCEJoFi0eb4wPeaH6yWwtWZmF soQAn3ClTbeLxF8fvFwV01LwiQ7lXT5H =WwzQ -END PGP SIGNATURE- -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ Freevo-users mailing list Freevo-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freevo-users

Do you have digital input/ouput on your amp/shuttle? I have two Klipsch speackers on an Onkyo receiver connected to my box with an SPDIF cable and it's quite satisfying. The advantage is that it works with surround as well. - -- regards, strawks -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmLYy0ACgkQ+2TXLlA5m7/VHgCfX3bWfYLerkSDMwAlqUgbtHhP tsUAn0Hopq6fle2x7HKVOn0TTcSHDHis =bbFN -END PGP SIGNATURE- -- Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
