Why does "ddrescue" fail for Audio Discs? (lemmy.ml)

I have an audio disc that I want to produce a one to one ISO of (it has some marks).

When I try to use "ddrescue" to copy it, I get the following error message. ddrescue: /dev/sr0: Unaligned read error. Is sector size correct?.

What am I doing wrong? I would assume "ddrescue" would automatically figure out the sector size.

To note, I want to use "ddrescue" because "abcde" keeps hitting read errors on the disk.

Edit:

Seems that "ddrescue" does not support audio discs (https://unix.stackexchange.com/a/558628).

And "abcde" already uses "cdda paranoia".

ddrescue doesn’t work properly on audio discs (even if you use the correct sector size of 2048 bytes). Have you tried something like cdparanoia https://www.xiph.org/paranoia/?
