Did anyone have sucess using these transmitters with RasPi running FPP 2.x?
Something changed with 2.x I was working with Dkulp, but he went on vacation and the emails stopped. I was able to use it with the usb connection with 1.x. Like you found that does'nt work with 2.x. So I purchased a soundblaster 3 usb audio adapter, and connected the audio out of that to the dsp pll transmitter, It works fine, maybe slightly worse audio than 1.x but acceptable. I kinda hate having the extra dongle hanging off the pi, but there seems to be no interest in fixing what was broken with the code. I did create a bug report #403. Several others commented about usb audio not working with any transmitter now. Maybe one day someone will fix it.

We've got several months left in this year...maybe the FPP guys can figure this out. This past season I used the same setup as you and everything was very clear.

Re: No Range at All.. Not Even 12 Inches...
This problem is in the USB subsystem or firmware and possibly not something that Dan or I can fix. The same is true for the longstanding robot sound issue with the Vast FMT-212R which I also have. A few years ago, I ran with a BBB master so I could use the USB input on the FMT-212R, but for the past two years I have just used the analog input with a Pi 3 B. Unfortunately, neither Dan or I (or Mat who was looking into this a few years ago) have the knowledge or time to look into the USB issue. We have opened a case with the Pi kernel/firmware guys but they haven’t come up with a solution yet and didn’t take Mat up on his offer to send one of them his FMT-212R to test with.

I am not sure I understand why it could be in the usb subsystem or firmware, it worked in 1.x and not in 2.x. Same pi, same hardware. Only thing that changed was the new FPP version. Could you clarify?

Re: No Range at All.. Not Even 12 Inches...
fpp 1.x and 2.x are based on different kernels. I gave up on usb audio and went to an audio pi hat. have not had an issue since.
2020 Full sized show reworked for the new location. Only adding (famous last words) 13 RBLs that I finally got converted to using pixels
2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show. Dim show (3000 pixels) had regular visits most nights.

Which exact hat are you using?

FPP v1.x used a Raspbian/Debian Wheezy Linux install with an older kernel. FPP v2.x uses Raspbian/Debian Stretch. In between Wheezy and Stretch was Jessie, so we jumped 2 major Operating System versions for v2.x. Wheezy was ancient, it had been around since before the first FPP release in 2013, we needed a OS upgrade.

Re: No Range at All.. Not Even 12 Inches...
Thank you for the response, it did'nt occur to me that the OS change was the main reason for the usb audio issues. Guess the audio dongle is the solution for now.
