Greetings (sorry this is a book),
I have been working with this for about two weeks now, I thought I could figure it out, but I am stumped.
I have a RPi3B+, DAC2 Pro and DSP Module, I cannot get any sound out of this combination out of either port of the DAC2 Pro. I know it is talking, as I can see it with 'aplay -l' (see below):
# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
Subdevice #0: subdevice #0
I have tried Volumio, and HifiBerryOS v20230404 and I even went back to HifiBerryOS v20111105 with the same result - silence.
With Volumio, I would get the alsa error if I chose 'HiFiBerry DAC Plus'. If I selected 'HifiBerry DAC' I would see it as Device2, but could not get anything out of it. (it is my understanding that it should be using dacplus based on previous threads, and google-fu).
I moved to HiFiBerryOS v20230404 with similar results. Diagnostics sees it as DAC+ DSP and I see it as noted above. I know they are talking, as when I am playing something the DSP LED turns on, and I have even uploaded v14, v13 and v12 of the DAC+ DSP Universal programs successfully. I tried test tones (1kHZ sine), nothing. Internet radio, nothing. FLAC, nothing. My amp is connected to a passive equalizer (as I like to see the music too), and have even tried multiple inputs on the amp (other sources in the same inputs work just fine).
Disappointed, I went back to v20211105 with the same results.
In both instances, config.txt has 'dtoverlay=hifiberry-dac'. If I manually change it to 'dtoverlay=hifiberry-dacplus', it will not boot, it hangs trying to start services. I have 'force_eeprom_read=0' as well. I have checked for output volume limits, but I see in 'journalctl | grep volume' that it is set to 99%.
I am stumped. I followed everything in the 'what to do if you have no sound' post, nothing.
Though rare, I think I may have a hardware problem, so I am turning to the experts to help me troubleshoot. Below is my Diagnostic Information.
Please review and let me know what you think. Thank you!
