Gqrx with fcd pro+ crashing in Linux Mint 16

[grege...@gmail.com]

I have been running gqrx in Linux Mint 15 with no issues .  Installed from your PPA onto a quad core AMD 64 bit machine.  I just upgraded this machine to Linux Mint 16.  I did a clean install, added your PPA as a source, and let it install Gqrx and its dependencies.  I did not have any other gnuradio stuff installed.

Now if I am using my FCD Pro Plus as a source, and I click on anything or even hover the mouse over an option while DSP is running, it will often freeze up and the terminal window will show the following:  audio_alsa_source[hw:1]: snd_pcm_readi failed: Input/output error.

If I enter my desired frequency, mode, gain setting etc before I start DSP and then don't touch anything, it will keep running.

If I use my RTL dongle as a source, I have no problems.

Do I need to configure a different audio sink or something?

I am using Gqrx 2.2 installed from PPA on 11/29/2013.

Thanks,

Greg Ella

I recall having some slightly similar issues at one point. I found that
setting the fcd device to Off in "Pulse Audio Volume Controller"
(pavucontrol) made things work better.

Hopefully that might help.

Nope, still crashes.

Guys,

Problem with the Funcube Dongle Pro+ on linux has been a known issue
since we added support for it, see
https://github.com/csete/gqrx/issues/91

Also note that on the website there is a link to known issues for
every supported device:

Crashes on AMD 64 quad core processor Linux Mint 16.  Works fine on laptop Intel i5 processor Linux Mint 16.

I run linux mint 16 (AMD x64 8 core processor) and had the usual problem with gqrx instantly crashing when trying to start with a fcdp+ in a USB 2.0 port. Its a well documented bug. Its not the same thing you're having, but it might be related. Try using it in a usb 1.0 port if your mobo has one. That's what I have to do.

"Fixed" the problem by switching to xubuntu 13.10.  Gqrx works fine now, and I have a desktop that I like for daily use.
