Hi,
I've recently gotten my RME Multiface up and working quite
satisfactorally with current Linux kernels. I'm very happy, especially
as I had a long run of it not working for some reason I never teased
out.
So, I find I can aplay and arecord, and I can use ecasound, and a few
other cli tools.
But, I can't use mplayer. Am I the only one? Anyone else tried mplayer
on the Multiface?
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
AUDIO: 48000 Hz, 2 ch, s16le, 1536.0 kbit/100.00% (ratio:

Meanwhile, aplay and ecaplay have no problems. So, I thought I should

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.

Hi, All:
Thanks to everyone who responded suggesting I start using jack to solve

Unlikely, Jack doesn't need X. But you shouldn't run it as root.
Starting as my ordinary user I get:
What options do you use ? You'll need at least something like
jackd -d alsa -d hw:NNNNNN
where NNNNNN is the name of the soundcard to use.
You can find out the name by running
aplay -l
(lower case L) The names you can use are those directly
following the card number, you should find your Multiface
in that list.
You could also use
jackd -d alsa -d hw:X,0
where X is the card number.
Jack has many more options, use
jackd --help
to see them.
And, things just sit there seemingly forever.
Which very probably means that all is OK. Remember that Jack is
a server. You keep it running and it will do its work. Switch to
another terminal for all other commands.
IIRC you wanted to use mplayer. To make it use Jack, do
mplayer -ao jack <filename>
Audio output should appear at line outs 1 and 2.

There is another solution, copy the following to a file
called .asoundrc in your home directory:
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
ctl.mixer0 {

Then start mplayer without the -ao jack. It should then
use the default ALSA card which we redefined to be a
virtual one connecting to Jack.

This may have to do with the 'port names patch' which seems
to be applied to your version of Jack. AFAIK it allows you
to change the names of the soundcard ports by creating a
file in ~/.config/jack. Maybe the file *must* be there, I
don't know, this is the first time I hear of this patch.
Could you try to get an unmodified version of Jack, if at
all possible jack1 (because I know that one better). You
currently have jack2.
Note: before installing any new version of Jack ensure that
any others are completely removed. Having more than one
version installed or even parts of another version always
creates strange problems.

May this be related with dbus support of jack2? If yes, then using jack1
or recompiling jack without dbus support might help. If dbus support is
needed without having X11 then there was a post on the topic by Len
Ovens ('Headless jackdbus (no X11)' on July 22nd 2013).

Dbus and X11 should not be related. Except that both the 'session'
dbus and X11 are probably launched by the same entity: the *DM
login manager. And I assume that Jack2 Dbus means 'session' bus,
and not the 'system' one. On a system without a graphical login
(as the OP is probably using) there may not be a 'session' dbus
at all.
I'll be optimistic and assume that jack2 really doesn't *need*
dbus even if it's capable of using it. Maybe I'm too optimistic.
Even if I've seen too much 'desktop', 'session', 'seat' and
whatever other nonsense creeping into a what should be a basic
system.

I have in the past been successful using dbus-launch to run screen on a

jackdbus from another (and other jack/dbus apps in other screen
terminals). Absolutely, there is no need for X to make dbus work. I did

Probably not. I don't know if running jackdbus is more or less useful in a
headless case. The major upside I can see is the ability to control the
running jack server from jack_control. Certainly jack_control stop/exit is
much cleaner than killall -9 jackd. If this is worth the added complexity
of having yet another service running, I don't know.
In any case, I would suggest chmod -x whichever executable you are not
using (jackd or jackdbus). Or if you are building jack2 just build the one
you want. (the debian jackd2 package is broken IMO for including both)

Hey Janina,
I suggest the same as Giso. If you are learning music, you might want to use other audio
apps at the same time anyway. So go for the JACK Audio Connection Kit. I've used it
ever since I started with Linux. I don't have an RME, but I have a multichannel audio
interface.
I hope this is a viable solution for you setup.

The last part is the operative part here -- using a Multiface as a
general purpose audio out will depend on all your apps all being able to
handle a single device with 18 i/o's. Some programs will handle that
better than others, and I've seen some fairly involved .asoundrc files
posted on here in the past to try and get around that for people who
really badly want it to be their general desktop audio device.
(PulseAudio handles the situation particularly poorly.)
It's probably best to let a motherboard sound chip do that and keep the
Multiface only for recording.

another computer). Multiface isn't really intended for end-user consumer-y
casual use, but is intended for multitrack studio & Multi I/O kinds of
things.

use other audio apps at the same time anyway. So
go for the JACK Audio
Connection Kit. I've used it ever since I started with Linux. I don't have
an RME, but I have a multichannel audio interface.
I have the Multiface II, and it's nearly impossible to address through raw
Alsa without some deep kung-fu. Though Jack you should be able to see all
of its i/o's and use it with MPlayer or whatever you want.

I've recently gotten my RME Multiface up and
working quite
satisfactorally with current Linux kernels. I'm very happy, especially
as I had a long run of it not working for some reason I never teased
out.
So, I find I can aplay and arecord, and I can use ecasound, and a few
other cli tools.
But, I can't use mplayer. Am I the only one? Anyone else tried mplayer
on the Multiface?
As others have already suggested: use Jack. For everything.
I have this alias for viewing videos:
alias vv='mplayer -ao jack -fs'
which works everywhere.

To avoid passing arguments or use an alias,
create a file "$HOME/.mplayer/config" that contains :
