No sound after installing multirom #15

After patching boot.img, the speaker does not work (usb-c earphones are working). Using Xiaomi MIX2S.

You may need audio firmware in vendor. Other devices also use it.

Does multirom modify the vendor partition? So what happens to the kernel and vendor when injecting boot.img? I flashed the original boot.img and the speaker works again. And injected boot.img affects both internal rom and secondary roms.

ARTI5T commented 5 years ago

By the way, is it possible to let every rom have a separate external storage /data/media?

It creates a mini-vendor partition for itself when encryption runs. That mini-vendor has to contain the firmware. Only then it can load it. No u can't have separate storage for every rom. Atleast not till now. It maybe possible however.

I didn't include decryption in my build and it always fail when I tried to add the .bin file to the installer. So how can I put something in ramdisk?

vasishath commented 5 years ago

No it won't work if u include the file in zip. This means your device needs speaker firmware early in the boot so u need to add a firmware directory to your device tree which include the bin file. And the flag MR_EXTRA_FIRMWARE_DIR to that.

OK. Thank you, problem solved.
