For me too. I have apdated from lineage os 18.1 official and now audio doesen' t work, now i'm going to use another phone until an update fix because i don' t want to loose all my data considering that i have done a dirty flash
Works fine for me after dirty upgrade. Have you installed latest MIUI 13 firmware?
So audio with LOS 19.1 works now that you use that firmware?I got it working again. Thanks all.
You have to install the latest firmware V22.214.171.124.SJKMIXM (https://xiaomifirmwareupdater.com/firmware/lmi/)
Because I already had installed LineageOS 19.1, I couldn't sideload it through the LineageOS recovery (spl downgrade error).
So I booted in TWRP and installed the firmware zip from there.
And now I have my audio back. I always thought that the firmware was included in the LineageOS zip package. But apparently not.
