audio distortion at AsiaStar uplink

There seemed to be considerable distortion in low frequencies, and M wanted the jingle during the start and end of Moments of Oneness to be broadcast undistorted. The line in the playout scripts was

mpg123 -o alsa09 -g 70 -q -a $DSP_DEVICE   "$line"

But the gain factor of 70% was not being set - probably some permissions issue. After IM and emails, L found the audio card bad, since using another one seems to give clear audio. But currently the DBMax is byepassed, so audio levels are sometimes low. Next task is to get it thru the DBMax.
