Version 2.0.992 for linux

[ahop...@googlemail.com]

Hi all,

there is a new version here 

https://www.sparksdr.com/download/SparkSDR.2.0.992.linux-x64.deb
https://www.sparksdr.com/download/SparkSDR.2.0.992.linux-x64.rpm
https://www.sparksdr.com/download/SparkSDR.2.0.992.linux-arm.deb
https://www.sparksdr.com/download/SparkSDR.2.0.992.linux-arm64.deb

not much new but it uses a new build system that allows more control of the glibc version so they should work on older distros.  The arm versions are now also built in the cloud with the x64 versions so it is far less effort to create them. If anyone wants an arm .rpm let me know and I'll add it to the build script as it is easy now.

There maybe a slight improvement in performance.

The last few versions used a statically linked version of portaudio, these revert to using whatever is installed on the machine (or installed as a dep of the package).

They all use Pipewire if available.

Alan,

 I installed Verion 2.0.992 on my Debian 12 variant of Armbian for ARM64. It would not run (segmentation fault see below) unless Pipewire was installed. This version seems to have fixed the audio dropouts. FM stereo is still wonky. Tested FT8 which ran well with my SDRplay RSPdx hardware.

On DietPi Bookworm Debian 12 without pipewire, Version 2.0.992 worked like Version 2.0.991.

Audio is occasionally choppy with the pulse device and the hdmi device does not work.

Hi Jerold,

thanks for the report.

It looks like the segmentation fault is caused because enough of pipewire was installed for me to detect it and use it when it is not actually running, I shall add more checks for this.

FM stereo works for me as long as the signal is strong so I'm a bit lost on this. I assume fm stereo is the same around the world? I'll have a think and see if I can add some logging to see what is going on.

Hi Steven,

thanks for testing, that at least indicates both the statically linked version of PortAudio and the version from wherever your distro got it from behave the same.

I've just setup a new multi boot card for my test rpi and have included DietPi, so I will have a play.
