Raspberry Pi 5, TYT 9000D, RIM-Alinco. I have no audio from radio when connecting to nodes or connecting to parrot. I also choose "force ID (local only) in allmon3, with no audio. You can see that the radio is transmitting.
I’ve had a similar issues with getting audio out from the TYT 9000D and Rim Alinco on HamVoip. It would work for awhile and then stop producing audio. I tried 2 different TYTs and sent the Rim back for testing.
I finally gave up and am going to sell the TYTs and maybe find a Alinco radio.

I have a TYT TH-9000D 220 radio, in service for a little under a year, which I no longer use in favor of an Alinco DR-235T, which I was lucky enough to find for a steal. Since the Alinco has discriminator, and the TYT doesn’t, it has much nicer audio, even post-filtering in software than does the TH-9000D.
Unfortunately, it also makes some weird popping and roaring noises as it transmits. This is common across all the DR-X35’s. This is especially true on higher power output levels, but still happens on low power. Putting a fan on it helps to an extent.
Anyway, after reading the first message in this thread, I hooked up my TH-9000D+RIM Alinco and tested it in both HamVoIP with simpleusb, and ASL3 with simpleusb and usbradio. It worked fine in all cases with ctcssfrom set to no.
On ASL3, I prefer using the usbradio driver. Simpleusb has some high-end aliasing that I can clearly hear in it’s lowpass filter implementation, and no rxsquelchdelay line.

Hello,
In my opinion, First, double-check all audio cables and connections between your Raspberry Pi 5, TYT 9000D, and RIM-Alinco. Ensure that the audio input/output settings are correctly configured in your software. Additionally, verify that the audio levels are not muted or set too low. If the radio is transmitting but no audio is coming through, it could also be worth checking your node and parrot settings in Allmon3.
I have setup a Raspberry Pie5 / TYT-9000d/ Rim-Alinco with these settings. Everything seems to be working correctly but i am getting low audio in even with rx voice level set to 999. Any help would be appreciated.
did you ever solve this… im having the same issue
Explain the detail of your setup and problem and
perhaps post your usbradio or simpleusb conf files
so everyone knows how you are setup to look for issues.
There are several problem post here and it is not clear which problem yours matches.
You will have to tell us your details.
I built 2 of the TYT 9000D. Same issue on the low output audio. I ordered LM386 Mono Audio Amplifier. If I recall I used 5v to power the amplifier. I used 12v to 5v stepdown converter to self contain the addons in the radio. Heatsink around the boards to protect from shorting. Wiring diagrams are all over the internet. Run the radios at med power with 120mm fan on top. It will last forever if using it as a simplex repeater.
I cant answer the no output. Didn't encounter that issue.
I used a TYT TH-9000D for a while. Didn't need any additional amplification. Audio level was reasonable in both directions, though the audio characteristics of that radio leave something to be desired. It works, but it has that typical Chinese bumpy resonant high pass sound that I don't particularly like, not discriminator.
I bought a RIM Alinco and the pre-wired pigtail from Repeater-builder.
At first, I had no audio and a bouncing PTT. I got another pigtail, which fixed that problem, but then I had a solid carrier but no audio. Everything else was working fine. I then got another RIM Alinco.
Turned out the original pigtail was incorrectly wired, and the RIM Alinco was bad, too.
I have since switched to using an Alinco DR235T running low power into an amp to avoid the radio making a bunch of weird noises, even though the power from the amp is about the same as the radio on high power. Still have the TH-9000D in a box.
I tried the original bad RIM Alinco on my DR235T when I got that radio, and got no TX audio with that combination.
I own the Alinco DR-135. It was new out of the box. I run it on a Winlink RMS station. I was questioning the 9000D, so I switched out the two radios. The 9000D was still not having enough audio to run packet and VARA using a sound modem and a dummy load for testing. I searched for a while to find a solution. Someone else had posted about the small amplifier and 5V. It works well. The Alinco DR-135 is a much cleaner radio and station. Anyway, I had the same setup with the Alinco RIM and pre-wired pigtail from Repeater Builder. Without the mini amplifier, it's not usable. I won't build any more unless it has the discriminator built into the radio. It was an interesting experiment. I'm looking for some other radios and will put the 9000Ds back to regular radio use. In conclusion, the 9000D is mass-produced, and it seems they are not all the same. Still a decent radio otherwise for normal use.
