[PlanetCCRMA] Re: HDSP9652 muted on system start

[Michele Spinolo]

Hi Dave,

I tried the trick you posted, but I am noticing some problems, probably due to some errors I am going in.
I added
hdspmixer >out 2>&1 /dev/null &
to my rc.local file, and I can get sound out without opening hdspmixer.

I am used to test my setup looping RME ADI-8 Pro input and output with Edward Wildgooses rec_imp tool (http://www.duffroomcorrection.com/wiki/Simple_Automated_IR_Measuring_Tool) which basicly plays and records a logaritmic sine sweep and extract the impulse response.
The problem raise when I use it just starting the system: I have clips on recorded impulse response (ADI-8 Pro inputs clips in analog domain), while it doesn't happen if I open hdspmixer.
I suppose the line
hdspmixer >out 2>&1 /dev/null &
set recording levels at a different value of -6.0dB which should be the default for RME HDSP9652.

Can anyone provide some hint?

Kind regards,
Michele Spinolo

Hi Michele

This is from a previous thread that you maybe missed.
(From Jamie Bullock 21/07/05):

Thanks for all the replies. I decided to have a look at this myself. If
you put the following in /etc/rc.local it fixes the problem (no annoying
messages either):

hdspmixer >out 2>&1 /dev/null &

Regards,

Jamie
