Re: 64bit testing

I have loaded wsjtx_2.4.0...  It runs fine. 

I can't get Audio {C-Media does not show either wsjt-x or Pulse} to work... {works fine 32 bit}

any ideas?? I have tried with/without Pulse Audio... 
The only thing I have NOT tried is to swap the USB audio module.  BUT, it shows (see above).
All I have changed is 32 bit to 64 bit...   (all 64 bit packages are up to date)
AND I thought I had audio working with Raspian.  I have also tried ubuntu 64 bit...

BAP: BTW, conky does not show temp.   I have added temp to the status bar.

An interesting write up on deep decode times on various Raspberry Pi hardware versions can be seen here but all results there are 32bit only:

Be curious to see back to back tests of the 32 bit build and the 64 bit for any differences in speed on the FT8.  The libraries you had to download to make the compile scripts work were all 32 bit.

I downloaded the latest May2021 raspberry64bOS (still in beta) and ran the script things seem to work for the most part


FL-suite needed a manual install of

to run the automated compile scripts, after added things seem ok!

qsstv has a hamlib-dev problem and JS8 package has issues it appears.

anyway I went down the path for better performance with FT8
