if you want to use the line out, use amixer to set the matrix mixer:

man amixer
and take a look at
http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=RME&card=Hammerfall+DSP+9652.&chip=FPGA&module=hdsp

amixer -c 1 cset numid=5 PLAYBACK_CH_1,ANALOG_OUT_1,5000
amixer -c 1 cset numid=5 PLAYBACK_CH_2,ANALOG_OUT_2,5000

5000 is some gain value, 32768 would be 0dB:
  0%     0 = -inf dB
 50% 32768 =    0 dB
100% 65535 =   +6 dB

instead of
PLAYBACK_CH_1, ANALOG_OUT_1, PLAYBACK_CH_2, ANALOG_OUT_2
you have to write the correct channel numbers. for a hdsp9652,
PLAYBACK_CH_1 is 26 and PLAYBACK_CH_2 is 27.

-c 1 is correct if the hdsp is the second soundcard in your system.


also make sure the line out is switched on, see:

amixer -c 1 contents

and search for line out, possibly it's numid=21

you can switch the line out on/off using
amixer -c 1 cset numid=21 0
or
amixer -c 1 cset numid=21 1
(assuming numid=21 is correct for your card)
