No line out, only headphone working on an ESP32 A1S audiokit board, V2.2 A149, ES8388, 2974

[KlausMu]

Hi,

I successfully compiled and flashed cspot on an ESP32 A1S audiokit board, V2.2 A149, ES8388, 2974.
So far everything works well, I can connect and play Spotify. Great!

But only headphones are working, line out is not working.
Is there anything I can do about this?

Thanks in advance
Klaus

glad to read you managed to compile cspot. i can reproduce your lineout 'experience'.

you can test euphonium: https://github.com/feelfreelinux/euphonium cspot is integrated there and line out is working over there (but no headphone...). But it's more difficult to get it up an running if you are using a windows pc.

For a deep dive in you can compare the slightly different drivers:

line out not working / headphone working:
https://github.com/feelfreelinux/bell/blob/4beaacf8c917255b6ac8219e82bc7a3c920a9b62/src/sinks/esp/ES8388AudioSink.cpp

line out working / headphone not working:
https://github.com/feelfreelinux/euphonium/blob/de9a20fd4e10e1719d265d36c649563d3b9a663e/euphonium/scripts/esp32/dacs/es8388_driver.be

the necessary registers are described here:

i would be glad if we could get lineout working.

Thanks for the hint. I gave Euphonium a try.
0.2.0 I cannot use, because of the missing DAC settings plugin
In 0.1.5 both headphone and line out are working at the same time. This version is a little bit unstable, maybe 0.2.0 is already better.

Release v0.2.1 with a fix. I'd love to hear feedback about stability! I'm trying to speed up the development of euphonium currently to resolve such issues.

[KlausMu]

Thanks for the new release, v0.2.1 is running now on my audiokit board. Bluetooth seems to be better, with 0.1.5 no connection was possible. But cspot still seems to be unstable. When surfing through different songs, playing every song for some seconds, after the fifth song or so, cspot crashes.

thanks for feedback! Can you provide me with the songs / playlists where the software crashes?

[KlausMu]

I think it is not related to any song or playlist. I really get it quite soon when I try to reproduce it. Just take any album and jump around in the songs. Sometimes it is needed to change the album, but I can reproduce it in less than a minute.

With cspot I get something like this:

ok, new master should improve stability. will make proper release this wekend.

[KlausMu]

Already tried it with cspot. A lot better, no more crashes so far, thanks!
Only two minor issues:

• when manually changing a song, there is always a short cracking that can be heared between the songs. Maybe it is possible to mute and only playback when audio is valid
• sometimes (every 10th song or so) when switching to a new song, it plays for the first two seconds, then a one second break, then song continuous
  But as said, only minor issues ...
