Hi,
I have just bought myself the Cardbus+Multiface RME system. I think I
have finally gotten the alsa modules (snd-hammerfall-mem and snd-hdsp)
to load correctly along with the OSS emulation modules. BUT I cant seem
to play anything out of the Lineout/Headphone output. I have tried
various 'amixer cset' commands but all I get is silence (trying to play
a simple wav file using aplay).
Any suggetsions?

dsen,
Hi. I'm messing with similar things this evening. (And not doing
great, but not failing either.) I'm using a HDAP 9652, not the
Multiface, but it's the same driver I believe. The difference is I have
no 'headphone output'. Just 26 outputs.
I'm in KDE. Inside of a Konquerer window, I have set the file
associations for wav and x-wave to be
aplay -device="plughw"
This seems to work all the time in a Konquerer window, but doesn't work
on a file just sitting on my desktop. Don't ask me why.
FYI#1 - make sure you don't have a blocking aplay sitting around. Do a
ps -aux | grep aplay
and make sure nothing is there.
FYI#2 - My headphones and main speakers are running off of playback_1 &
2.
Good luck,
Mark

actually, i doubt that this is the issue at all. the hdsp driver has a
module option:
snd_line_outs_monitor
(possibly changed in recent versions to just "line_outs_monitor"). if
set to a non-zero value, all other outputs will be monitored on the
headphone/line out channels. you can find out about module options
using the modinfo command. for example:
% modinfo snd-hdsp
filename: /lib/modules/2.4.19/kernel/sound/pci/rme9652/snd-hdsp.o
description: "RME Hammerfall DSP"
author: "Paul Davis <pbd(a)op.net>"
license: "GPL"
parm: snd_index int array (min = 1, max = 8), description "Index value for RME
Hammerfall DSP interface."
parm: snd_id string array (min = 1, max = 8), description "ID string for RME
Hammerfall DSP interface."
parm: snd_enable int array (min = 1, max = 8), description "Enable/disable
specific Hammerfall DSP soundcards."
parm: snd_precise_ptr int array (min = 1, max = 8), description "Enable

parm: snd_line_outs_monitor int array (min = 1, max = 8), description "Send
all input and playback streams to line outs by default."
parm: snd_force_firmware int array (min = 1, max = 8), description "Force a
reload of the I/O box firmware"
the parameter defaults to zero, so by default, you hear nothing.
there is no way to use any existing linux audio mixer to control
*what* you hear - the hdsp has 1542 mixer controls arranged in a
matrix, and its just not possible to make sense of this with mixers
designed around a few channels with direct routing. work is proceeding
on an equivalent to RME's TotalMix to offer ways of controlling this.

Hmm I do use line_outs_monitor=1 as a module option on loading snd-hdsp.
gamix shows that all the channel volumes are loud enough....The various
'play' (aplay, etc) doesnt complain (keeps on playing stuff without
falling out) yet all I hear is silence.
gamix shows the 'passthrough" to be disabled. Is that some indication of
whats going on?
The other indication is that gamix crashes immediately upon my trying to
play something. (It has no problems when I invoke it. Only when I try a
second application to play a file).
Do I need to do something like 'amixer cset numid=5 26,26,32768'?
How do I play something out through the SPDIF/optical or ADAT ports?

by editing /etc/modules.conf or its equivalent on your system, and
adding:
options snd_hdsp line_outs_monitor=1
this will take effect the next time the snd-hdsp driver is loaded.

no, i told you already: if line_outs_monitor isn't set to a non-zero
value, then *nothing* will be routed out of the line out channels. if
its set to a non-zero value, then all playback and input channels will
be sent to the 2 line out channels at unity gain, mapped using a
conventional stereo setup.
the only controls that gamix shows are a small set created
specifically to allow limited control from the existing set of linux
"mixer" apps. they control *only* the volume of the computer-generated
data stream (0..N) sent to the matching output (0..N). they do not
affect any other aspect of this extremely powerful mixer.
How do I play something out through the SPDIF/optical
or ADAT ports?
you have to define this question more precisely. using the "plughw"
device will duplicate the signals across all channels. its extremely
unlikely you can use the "hw" method, since this requires
non-interleaved, 24-in-32 bit, 26 channel sound, and i doubt you have
any files like this on your system. this is a generic ALSA question,
and one that needs (like most of ALSA) to be better documented. the
"hw" access method requires a hardware configuration (sample rate,
sample bit width, interleaving, channel count) that is directly
supported by the hardware - no format conversion is done by ALSA at
all. by contrast, the "plughw" access method will convert between just
about any requested format (eg. stereo 16 bit interleaved data) and
something supported by the hardware. i repeat: this has nothing to do
with the hammerfall - it applies to all ALSA support devices. the same
is true about the methods of defining devices corresponding to
specific output channels. this is a generic ALSA question, and i don't
have time right now to answer it.

I think you mis-read my email. I said I *do* set line_outs_monitor=1
(and still get silence)

Do I need to do something like 'amixer cset
numid=5 26,26,32768'?
Maybe you'll have to tell amixer which card to use (HDSP vs. internal
laptop card). If your HDSP card is alsa card #2, then the command will
be:
amixer -c 2 cset numid=5 26,26,32768 (playback one to line out left)
amixer -c 2 cset numid=5 27,27,32768 (playback two to line out right)

i'm not clear that the channel IDs are right here. what made you
suggest those values thomas?

first value: input source
second value: output source
third value: gain
input source: 0-25 (physical channels), 26-51 (audio output streams)
output source: 0-27 (physical channels)
output channels 26 and 27 are the two line outs on the I/O box.
Maybe the term playback wasn't clear. I meant "audio output streams".
(Playback is Totalmix terminology, I must be obsessed at the moment :)

Paul,
Great info. I didn't know about modinfo. Is there a way to query what the
current setting of these parameters are? It seems that I'm told I have a
range to work in, like 1-8, but no indication of how they are currently set
or what they do. (Maybe only read the code?)
I'm sure that many are just on/off sorts of things, but some clearly are
not.
Mark
