[Chris Smith]

Hi John

After that little interlude I started linHPSDR from the desktop icon and the option has reappeared!

Weird!

Until a day or two ago, on the Rx-0 config page (I think) I used to have a box I could tick to send the audio to a local device - in my case the speakers in my 27” monitor. However last time I started linHPSDR this config option was not present and I had to use the 3.5mm o/p jack on Mercury. Is there some magic setting for this? It’s possible some s/w update has disabled the audio device on my PC.  I wondered if you’ve had any experience with this happening?

Same changes to the “Prerequisites for building" saw a very rapid build and install of both wdsp and linhpsdr. I must check my $PATH environment as I had to add a symbolic link to the wdsp library in /lib64 to /usr/local/lib.
