I've been experiencing lack of/sporadic metering on hdspmixer too..
I'm running Debian testing with kernel 2.6.8 (same effect with 2.6.3),
with both the debian alsa packages and a locally compiled latest alsa
version...

I had no such problem using 2.4.xx series kernels, although I was using a
pre-1.06 version of the alsa drivers..

I really don't want to start rolling my system back to older kernels, but
if thats what has to happen, so be it.

I've tried fiddling with PCI latencies and I've also tested the hdspmixer
using OS/X to see whether it is some bizarre heat related h/w problem
(it's damned hot in this bus!)

There is no appreciable quality problems with the routed audio, but it's a
bit disconcerting not being able to see levels (and a bit embarrasing
doing live events!)

If anybody has any further information on this, or wants me to provide
more information, let me know.

Regards,

Iain

Are you using ppc?  I found a bug in hdsp driver that it doesn't
handle big-endian correctly in the metering mmap.
Could you try the CVS version?

I'm using intel architecture... (Inspiron 8500 with 2GHz P4 M)

I've tried the CVS version, and still get the same results.

How about the attached patch (to cvs) ?

OK, I'm not familiar with the build process for this yet, but I did the
following:

cd alsacvs
patch -p0 < path/to/patch.txt
cd alsa-driver
make clean
make
sudo make install

Rebooted...

And excellent stuff, I now get sane (looking) mixer levels all over the
place :)

Now that I can see the levels, I notice that all 8 analogue ins are
sitting at about  3/4 of the way up (showing about -6.60 variable) with
nothin plugged in to them... no audible noise coming through.. I guess
this is not related though... I'll investigate later.

Thanks very much indeed :)

Iain

Aha.. OK, so my excitement may have been a little premature :)

Now I have the 8 inputs showing a high level (3/4 full -6.59->6.8) on the
8 analogue inputs of my multiface (even though seven of them are not
plugged in).. the line in 1 is connected to powered Miq, and the yellow
RMS bar seems to be doing the right thing, but is always below the green
peak level meter.

The audio itself sounds very good to me on all counts.

When using xmms/jack, or aplay -D plughw:0,0 some_file.wav, the left
playback channel is flickering right up at the top (not peaking red
though), whereas the right channel (playback 2) is not showing anything
for peaks at all with the green meter. The right channel is also showing
-120.6 - the left is showing 0.0. I can hear sound for both channels as
normal.

When routed the analogue inputs or playback channels to analogue out 1/2
and the line outs, the meters look pretty normal to me on the bottom row,
and the yellow RMS bars seem much more reasonable on the playback and
analogue ins than the green (peak) level meters.

Regards,

Iain

Hmm, it looks like we still have small problems...
Maybe Thomas has better clue (I have no RME h/w).

Anyway, I already applied the last patch to CVS since it improves (at
least for you :)
