Worth noting that this issue only appears to occur when the fkms ("fake" KMS) overlay is in use on the Ubuntu Desktop for Raspberry Pi images. Under the kms ("full" KMS) overlay, the audio is fine. While kms is indeed the default overlay, it is likely (due to LP: #1946368 on impish) that many may be using fkms as a workaround.
