[linux-audio-user] HDSPmixer problem

[Mark Knecht]

Hi,
   Family member with the HDSP 9652 using the same kernel but using
Planet Alsa support. Possibly your RPMs might have something to do
with this?

   To me this sounds like a firmware revision issue. Check with other
MultiFace users as to which revision they are using.

Seems a bit strange. Default operation on my copy is that the
input/top row routes nowhere, so for input audio I have to select
where you want it to go and bring the level up before I see anything
in the bottom row. Note that if you choose a route but do not bring
the level up on the top row then the next time you look it's not
selected.

Default operation for the internal audio is vertical routing.
1-internal goes to 1-output, 2-internal goes to 2-output, etc. Default
levels are set correctly for this. This way if you choose a default
app it routes to internal 1/2 and you see output 1/2 with the same
value. Hook your output D/A there and you get sound. (Supposedly!) ;-)

I see the yellow peak about 1/4" above the top of the green VU moving
as the audio does.

Is it set non-threaded?
