Possible FreeDV crash when adjusting audio settings with pavucontrol

From FreeDV Reporter earlier:

[Tyrbiter]

I have just tried the very same thing, this used to work in the past and now I get a segfault, here is gdb's output when it happened, seems to be a threading issue in StartRxStream where it's trying to change the soundcard out name:

PulseAudioDevice[Tue Jun 6 19:32:52 2023]: stream named alsa_output.usb-Generic_Realtek_USB2.0_Audio-00.analog-stereo has been moved to alsa_output.usb-1130_USB_AUDIO-00.analog-stereo

I have the same problem with frequency reported as 0Hz to FreeDV Reporter. Sometimes it works, sometimes it doesn't. Toggling Stop/Start usually updates the web page with correct frequency. Updating the report frequency box manually, or selecting a predefined frequency in the menu works too. Like LU3JIJ, I'm not using CAT so my radio is never polled via hamlib. I'm using FreeDV v1.8.10.1 on win10 at the moment.

[tmiw]

Thanks for the stack trace, @Tyrbiter. Based on it it looks like something changed since the feature was written that's causing memory to go out of scope. Should be a straightforward fix, let me try something real quick.

[tmiw]

@JohBod, I took a brief look and it looks like it should be working, even without hamlib turned on. I'll have to investigate more tonight (not at home).

[JohBod]

@tmiw, I have seen many stations reporting 0Hz on the web page and I suspect that some of these zeroes were caused by this elusive bug. The path from the "Report Frequency" box to the web page is quite long, maybe the problem is not in the FreeDV-GUI code?

[Tyrbiter]

It should be possible to capture the network packets using Wireshark, that would definitively identify if freedv-gui is sending 0 or not.

[tmiw]

With Hamlib disabled, I can duplicate the issue @JohBod described but it's very much intermittent; I need to push Start/Stop multiple times for it to happen. I'll tweak some stuff to hopefully help.

[tmiw]

With the changes in #421, I didn't notice 0 MHz being reported after repeatedly connecting and disconnecting 20+ times in a row. (Previously it was happening maybe once every 3-5 connections.) Let me know if that works better for you guys as well.
