After updating my laptop to debian 12, i no longer get any output from my device, when use the device through rtl_tcp, i do get output.

rtl_tcp: Interrupted system call

I am sure it is something i am doing wrong, but cant seem to figure it out? Anybody know what i am doing wrong?

Strange. Try also with -Y autolevel -M level -M noise to report signal strength -- there should at least be that in the output then.

Current noise level -42.1 dB, estimated noise -42.1 dB

That is dead silence for 8-bit receivers (RTL-SDR). There is radio data incoming but it's all 0's.
You can record a file with rtl_433 -d 0 -t biastee=1 -w file_433.92M_250k.cu8 -T 5 then drop on https://triq.org/pdv/ -- it should be "blank" (e.g. not a spectrogram/waterfall like you expect).

No idea if the incoming radio frames are 0's or the data is corrupted somehow. Perhaps build the current version, the SDR input was rewritten. (No need to install if you don't like to, just run ./src/rtl_433 from the build dir.)

Building the latest rtl_433 did not have any different results, i did find a solution though. I had originally built the the rtl-sdr driver from rtl-sdr-blog, After uninstalling that driver, and installing the driver from the debian repository, everything worked as expected. Thank you for your time and effort. :)

This could be a general problem then? Do you know which version, date, or git tag the problematic rtl-sdr-blog driver was?
