Error starting sBitx v4.3 64 bits

[email protected] All Messages By This Member #115942 Good afternoon, I had a Raspberry TFT screen saved and today I put it on a sBitx computer version DE. ? But now a problem has appeared, the sBitx does not start and gives the error "snd_mixer_selem_has_capture_switch: Assertion `elem' failed". ? pi@sbitx:~ $ cd sbitx pi@sbitx:~/sbitx $ ./sbitx sbitx v4.301 Unable to load ~/sbitx/data/hw_settings.ini Loading default_hw_settings.ini instead i2cbb.c:writing address failed at 8 sbitx: simple.c:652: snd_mixer_selem_has_capture_switch: La declaración `elem' no se cumple. Abortado pi@sbitx:~/sbitx $? ? ? If I disconnect the power supply from the TFT screen and restart the computer everything works correctly. ? The Raspberry is a v4, the OS is 64 bits and the sBitt version is 4.3. Any ideas? ? Thanks, 搁补尘ó苍 EA4GZI
JJ - W9JES All Messages By This Member #115943 It appears that there is sound on the TFT you are using and the Pi is recognizing it. You can run aplay -l from the terminal to verify. You must have the Wolfson Audio chip mapped as the first device or sBitx won't start. ? card 0: audioinjectorpi [audioinjector-pi-soundcard], device 0: AudioInjector audio wm8731-hifi-0 [AudioInjector audio wm8731-hifi-0] ?

Evan Hand All Messages By This Member #116020 Hi Ramon, ? Try adding noaudio to the vc4-hdmi (not sure this is the correct name) line in the config.txt file in /boot.? I had to do that for an external HDMI monitor with audio. ? I still need to shut down and wait to restart my DE.?? ? I also suggest going to JJ's 64-bit software.? My DE seems to like it better. ? 73 Evan AC9TU
