Hi,
The question is : How config alsa to have spdif used by xine and mplayer.
My suspicion: I have no controls IEC958 threw "amixer controls" ???
I just installed last dev release 1.0-pre1 (with alsa-driver-1.0-pre2).
Technical data of my hardware and system configurations are at the end of the
mail.
Compilation and installation worked perfectly.
The only problem I have (and it might not be linked to this release version),
is in configuring my .asoundrc to have spdif work with xine, xmms, or
mplayer.
I expected to run xine and have 5.1 outputs on spdif with divx and the same
with mplayer.
But it is not the case
I tried:
mplayer -ao alsa9:nforce divx.avi
mplayer logs:
---------------
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit
(Little-Endian)
alsa-init: soundcard set to nforce
alsa9: 44100 Hz/2 channels/4 bpf/16384 bytes buffer/Signed 16 bit Little
Endian
AO: [alsa9] 44100Hz 2ch Signed 16-bit (Little-Endian) (2 bps)
But it goes to my analog speakers.
The same with xine:
xine divx.avi
logs:
------
main : détection du plugin de sortie audio <alsa>
audio_alsa_out : supported modes are 8bit mono stereo 4-channel 5-channel
5.1-channel a/52 and DTS pass-through
[...]
audio_alsa_out: Audio Device name = default
audio_alsa_out: Number of channels = 2
I test with aplay:
aplay -D plughw:0,0 test.wav: OK. Goes to my analog speakers
aplay -D plughw:0,2 test.wav: OK. Goes to my 5.1 speakers
I have read maybe every post, and docs available, but I didn't reach a config
that enables spdif with 5.1.
My .asoundrc:
------------------
pcm.nforce-hw {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "nforce"
}
pcm.nforce {
type dmix
ipc_key 1234
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
}
ctl.nforce-hw {
type hw
card 0
}
In fact, I can have results out threw spdif (so with 5.1 speakers) by setting
in .asoundrc the pcm "hw:0,2" instead of "hw:0.0", what means, I think, the
spdif CAN work.
But even though the sound goes to my 5.1 speakers, the system still is not
spdif apparently:
I say that because of this mplayer's logs, after the command:
mplayer -channels 6 -ao alsa9:nforce divx.avi
alsa-init: requested format: 44100 Hz, 6 channels, Signed 16-bit
(Little-Endian)
alsa-init: soundcard set to nforce
alsa-init: unable to set channels: Invalid argument
Could not open/initialize audio device -> no sound.
If I don't specified 6 channels, it works but with 2 channels (that outputs
threw my 5.1 speakers because of my trick on .asoundrc):
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit
(Little-Endian)
alsa-init: soundcard set to nforce
alsa9: 44100 Hz/2 channels/4 bpf/16384 bytes buffer/Signed 16 bit Little
Endian
AO: [alsa9] 44100Hz 2ch Signed 16-bit (Little-Endian) (2 bps)
Building audio filter chain for 44100Hz/2ch/16bit -> 44100Hz/2ch/16bit...
xine neither works with 6 channels (but the sound still outputs to 5.1
speakers) :
it detects alsa:
main : détection du plugin de sortie audio <alsa>
audio_alsa_out : supported modes are 8bit mono stereo 4-channel 5-channel
5.1-channel a/52 and DTS pass-through
[..]
audio_alsa_out: Audio Device name = default
audio_alsa_out: Number of channels = 2
but thinks it is 2 channels.
Moreover, this tricks disabled the volumes controls from xine or xmms, or
alsamixer.
I thought if I didn't have .asoundrc, alsa would work with default
configuration, but I don't know how files from
/usr/share/alsa/cards/NFORCE.conf are involved in setting the configuration.
Yes, you guess I have nforce.
I then terminate with my hardware and system configuration:
