Sorry, I didn't realize that ac3dec supports passthrough with the -C
switch.

I'm afraid that is a hardware problem and there's no software solution.

Sorry, I must respecfully disagree. I've just tried this command:
$ ac3dec -C en.ac3
Using PCM device 'plug:iec958:{AES0 0x2 AES1 0x82 AES2 0x0 AES3 0x2}'
AC3 Stream 48.0 KHz 384 kbps
And I can see the dolby digital AC3 indication on the display of my
Yamaha DSP-A1 amplifier which means the passthrough is workign fine.
(of course without taking into account the sata pb that's plaguing me
;-) )

Depends on the receiver. Some play the stream even if non-audio is not set. It could be that non-audio is not set, but receiver detects DTS but not DD if the non-audio bit isn't set. There exist DTS-Audio CDs, which means instead of PCM DTS streams are recorded as CDDA tracks. So here the receiver can't rely on the non-audio bit.

Is AC3 the DVD > standard (I didn't think so...)? I'm not really a home theater expert, but the DVD standard is AC3 which is also known as DD. DTS is an older, less common format. So you should be able to play DVDs in surround. I'm not sure why the other file didn't work. It looks like mplayer tried and failed to guess the file type? I *think* that if AC3 passthrough works then DTS must work - it's just a matter of setting a non-audio bit on the stream. Lee - Using Tomcat but need to do more?

It has a slightly different output when I do the following:

Re: [Alsa-user] Surround sound via optical spdif out
just to chime in ... I have a similar pioneer look on your display, where the little digital / analog display box is. when receiving a encoded pcm bitstream, the display will show: DOLBY DIGITAL or DIGITAL DTS depending on the encoding used... when a normal non-encoded pcm is received the indicator will just read DIGITAL gordon On 10/13/06, Nathan A.

Does the receiver indicate an AC3 signal rather than standard PCM? IIRC AC3 passthrough might not work on nvidia chipsets due to a proprietary hardware implementation, but it might have changed.

[Alsa-user] Surround sound via optical spdif out
Hi, I am running a mythtv box based on Mandriva 2007 on a AMD 3200xp (Dual core) on an AM2 chipset. I am attempting to get surround sound audio out to my stereo via an optical s/pidf cable. With some help from kirberich && crimsum I adjusted the model= line in my modprobe.conf and applied the patch from http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=e51177a60747522a60bc1599aa5b2db22d4770a4;style=gitweb Unfortunately, I still am unable to get surround sound to work. The way we were testing this is with "speaker-test -Dplug:iec958 -c6" (note: iec958 and spdif are the same for this motherboard). I am getting sound from my left and right speakers, but nothing from anything else. So any more troubleshooting help would be greatly appreciated.
