Rpi5 no audio

[MADDninjatherapy]

Im probably just bein really dumb, i havnt done much with raspberry pi systems. I cant seem to get any audio to go through, im trying to get the audio to be output through an innomaker hifi dac hat pcm5122 (https://a.co/d/0dPF2siL) and im trying to get that audio through my cars fm transmitter (https://a.co/d/0cp4ankd) but no matter what ive tried it doesnt seem to want to work, the dac hat lights up like its outputting audio but i cant hear anyting, ik i have a ground loop issue as evident by when i was using a 3.5mm jack to 3.5mm jack cable (there was the satic humming from the ground loop) but when i was using an RCA to 3.5mm jack cable the static humming was quiet if not gone. But still no audio, I made sure the dac is default, i2s is enabled, i changed "playbacksinkname" to my dac hats name (something like alsa_output.platform-107c7000soc_sound.stereo-fallback), volume in alsamixer and hudiy ui (on the screen) is set to 100%, im stumped rn lol, any help would be GREATLY appreciated, Thanks.

Do you have a microphone input in your setup? If not, as a first step, try not loading the echo-cancel module at all. Based on forum feedback, PipeWire's echo-cancel module can cause various strange issues (especially on Trixie) when it's loaded but there is no actual microphone input in the system. In this thread, you can find an example $HOME/.hudiy/share/hudiy_startup.sh script that does not load the echo-cancel module and uses a "dummy" microphone instead:

I plan to have a usb microphone plugged in, just didnt have it plugged in for now, so should i try plugging that in and seeing if it happens to fix anything that MAY be caused by the echo-cancel module?

Yes, you can plug the microphone or modify hudiy_startup.sh to unload the echo-cancel module and load the "dummy microphone" instead.
