   Hi Arie,

   Yes, I managed to download the 4 packages after all.

   Are you running LINRAD on a laptop?
   Is the output on the PCM port enough to drive the
   amplifier in the speaker boxes?.

   So let me get this straight. Audio from rx into
   MIC and processed audio out, on the PCM port?
   And the ALSA mixer lets you set this?
   Although Roger, W3SZ has the opinion that the problem
   exists because of the use of VGALIB. Are you using VGALIB
   with Linrad on you laptop or desktop?
