New Stereo soundcard, no sound through RCA input.. Any help appreciated.

Post by UFO-Rpi3b5000 » Wed Oct 31, 2018 1:44 am

I only just recently brought the Audio Injector Stereo Soundcard, to try to boost the dud sound quality of the Rpi 3B.Though still a week later I am unable to get it to play any sound out of the RCA output like it should. However I had some luck getting it to play through the headphone jack w/ a set of headphones. Please give me any advice you can, I don't want to have to listen to my Pi through the headphones all the time lol!
I'll try to post a screen of the aplay -l, dmesg | grep "audio" & my alsamixer results. I appreciate any support.. Cheers

This'll do it. I came back to this forum because I had the same problem and somebody told me what to do, and it worked. I just finally got around to a full "production" test tonight. So, whoever it was that helped me so many months ago, thanks. I presently can't find the file that would have had the info on who to properly credit. Sorry. Mea culpa maxima.

Before you try to get the RCA inputs to work, do this:

/usr/sbin/alsactl --file /usr/share/doc/audioInjector/asound.state.RCA.thru.test restore

Since I'm running a C++ program, I insure that I do this by calling system() w/ the right stuff.

BTW -- i believe the card/HAT reverts to using the default inputs every chance it gets, so don't be surprised if you have to keep doing this. Mine was stable for 3 hours in my production test.

I was having sound issues [no sound] after installing a realtime kernel. This method fixed it! Thank you so much!
