Topic: Hammerfall HDSP 9632 Recording Line-In (volume too low)
Hello,
the company I am working for has recently bought a HDSP 9632. We want to use it to stream sound, captured
on the Line-In, over a multicast channel to an array of Set-Top-Boxes...
arecord -Dplughw:0,0 -f S16_LE -r44100 | cvlc -vvvv file:///dev/stdin --sout '#transcode{acodec=mpga,ab=128,channels=2}:duplicate{dst=std{access=udp,mux=ts,dst=239.7.7.7:6970}}'
is doing the job perfectly (Strangely VLC 1.0.3 cannot handle this device (alsa init problem) directly therefore
arecord).
Our problem is that the sound recorded this way has a very low volume. The Line-In on the sound card is fed
by the output of a satellite receiver. We are using CentOS 5.4 x86_64 and ALSA 1.0.17
Even with Input Level set to -10 dBV using hdspconf, the volume of the registered sound is pretty low.
We would like to know if there is a way to correct that.
Thank you in advance!
Regards,
Helmut
