hwac3 big endian AC3 not supported , alsa / aureon 5.1 sky (SPDIF)

[ilkka@…]

Hi

I came up with a problem with hardware ac3 passthrue (hwac3) with alsa 1.0.5.
In my previous mplayer version this was working (i think it was 0.93 version)

problem:
[format] Sample format big endian AC3 not yet supported
Couldn't find matching filter / ao format!
-- and no sound

some maybe usefull logs ran with "mplayer dvd://4
-ao alsa:mmap:noblock:device=mplayer -ac hwac3 -v"

Aparently this bug includes way too few information. Letme refrase this whole thing.

What did you want it to do if I may ask?? -ac hwac3 will cause MPlayer to try to
use S/PDIF output, which seems to fail with your card/config.
With current CVS setting a device for hwac3 will work, but unless you have a
hardware ac3 decoder plugged into your soundcard that won't be what you want.
Anyway, why do you use the "plug" type instead of letting MPlayer do conversions?

[Dominik 'Rathann' Mierzejewski]

Fixed in current CVS, then? Closing.

[reimar]

Hard to tell if it is fixed, as I don't know what exactly the user wanted...
But it probably is fixed in CVS...
