[MPlayer-users] Clicking while playing high-res audio

[Shane W]

Hey all,

So I nearly have this working, high-res audio streaming via
HDMI from the computer to an AV receiver.  Mplayer is
giving one last trouble spot though, at least I think the
problem is with mplayer.  When playing a 6 channel, 96kbps
mlp track from a DVD-audio disc, I get little pops rapidly
throughout the track.  If I use mplayer -ao pcm to decode
the mlp to wav and then play that wav, the popping is less
noticable but is still present.  I figured at that point it
was a cpu issue but my load average never exceeded .10 on a
dual core chip.

My mplayer commandline is:
mplayer -ao alsa:device=hw=0.3 -channels 6 \
-af channels=6:6:0:0:1:1:2:4:3:5:4:3:5:2 test.mlp

The -af channels bit is to workaround an issue with the
current Intel hdmi audio implementation.  It has a
different idea of channel order than does ALSA as far as
the hdmi output goes.  If I use a lower sample rate (-srate
48000), the popping appears to go away, I can't hear it at
any rate.  I also don't hear the popping when using aplay
to play the wav but I can't be sure since I can't do the
channel mapping with aplay.

Does anyone have any ideas on this one?  The mplayer
version is svn r29105.  The sample format is 96000, 6
channel 32 bit.  Well I believe the DVDA is only 24 bit but
mplayer says 32.
