Hi, All:
Thanks to everyone who responded suggesting I start using jack to solve
my problem with mplayer and my Multiface.
Trying to start jacd from the command line as root I fail for lack of an
X-server.
Starting as my ordinary user I get:
no message buffer overruns
JACK server starting in realtime mode with priority 20
audio_reservation_init
Acquire audio card Audio8
creating alsa driver ... hw:8|hw:8|256|2|48000|0|0|nomon|swmeter|-|32bit

And, things just sit there seemingly forever.
All suggestions much appreciated. Please note I can't use gui tools as
none are Orca friendly, afaik.

But, I can't use mplayer. Am I the only one?
Anyone else tried mplayer
on the Multiface?
I use mplayer with the jack backend on a RME hdsp card without problems.
I can reproduce the problem you describe with the alsa backend.
-- Giso
For cli tools mplayer gives me the ability to pause, or move backwards
and forwards through the audio file. This is important to me because I
learn music these days by ear.
I know one can do this in the gui, but as a blind user the Linux gui
audio apps aren't particularly friendly in my experience. Besides, it's
so terribly simple, if rather imprecise, to use spacebar, left-arrow,
and right-arrow.
The error I get:
Opening audio decoder: [pcm] Uncompressed PCM audio decoder

Meanwhile, aplay and ecaplay have no problems. So, I thought I should
ask if anyone else has experienced this before reporting to mplayer
devs.
TIA
