I\'ve found that when I play a DVD, in order to send the AC3
soundtrack out my spdif unaltered, I need to use
mplayer -dvd 1 -alang en -ac hwac3 -af-adv force=3
If I omit the -af-adv force=3, mplayer fails with the following messages:
alsa9: 48000 Hz/2 channels/4 bpf/65536 bytes buffer/Signed 16 bit Little
Endian
AO: [alsa9] 48000Hz 2ch AC3 (1 bps)

AO: Comment: under developement
Building audio filter chain for 48000Hz/2ch/16bit -> 48000Hz/2ch/8bit...
[dummy] Was reinitialized, rate=48000Hz, nch = 2, format = 0x00000020 and bps
= 2
[libaf] Adding filter format
[format] Sample format big endian AC3 not yet supported
Couldn\'t find matching filter / ao format! -> NOSOUND
Uninit audio filters...
[libaf] Removing filter K KI
and then it goes on to crash with a signal 11.
Is this a known bug/feature?
I\'m running linux kernel 2.4.19 with alsa 0.9.0rc6 modules
and MPlayer 0.9.0rc3
hardware is P4 1.6 with Abit SD7-533 onboard cmi8738 sound
with spdif out to an external AC3 decoder/amp.
