[x86-64] No Audio After Upgrading to LE 12.0.2

  • Hi folks,

    Feeling pretty silly here. I had LibreELEC working perfectly on my Intel NUC (nuc7i5bnb) but my SSD died. I didn't have a backup (my bad) so had to start from scratch. I'm not entirely sure what version I was running, but pretty sure it was 11 something. Anyway, I decided to go for latest (12.0.2) but have been unsuccessful getting my audio to work.

    My NUC is connected via HDMI 1 to my sound bar, so pretty sure all I did to get this working previously was set the audio output to HDMI 1. But this time around, no dice.

    I tried disabling Audio DSP in BIOS settings but it didn't help. Also tried updating the BIOS since it was quite old.

    Can anyone please help me diagnose?

  • I don't see anything 'wrong' in the log, so first thing I'd do is update to the latest LE13 nightly image from https://test.libreelec.tv to see if the newer kernel/firmware used magically fixes the issue?

    Thanks chewitt. I switched to nightly and it worked, although I had to choose HDA Intel PCH SII SII SPRT RPT on DisplayPort #0 for reasons I don't understand. Perhaps I also had that option chosen in my V11 install, but certainly in V12 I tried everything just in case and it wasn't working.

  • The NUC supports both DP and HDMI output, but it was cheaper for Intel to implement the HDMI tranceiver using an LSPCON chip that converts DP to HDMI so both outputs can be handled in a single chip. The GPU still has an HDMI capability which shows up in the kernel (unless you manually disable it in kernel boot params) but this is not wired up to anything.

    NB: It may have worked on LE12 under the DP output too .. maybe?. No harm in staying on the nightly if it works though. Kodi will move to wrap up development on Piers soon and then there'll be an official release to update to.

    Ah, that makes sense.

    I'm quite certain I checked every option, but I may have accidentally skipped one.
