Description
Hi all,
TL;DR: Encoding with 1.3.1 Opus encoder and decoding with 1.1.2 Opus decoder results in extremely bad / distorted audio.
When we encode the audio with 1.3.1 Opus encoder (on 20.04), and decode it with 1.1.2 Opus decoder (on 18.04) - we get very distorted sound.
When we manually cloned the Opus git repo, and built v1.1.2 on the 20.04 machine - the resulting sound quality was good.
- Do you know why we are experiencing the distorted / bad quality audio? Are 1.3.1<>1.1.2 incompatible (I didn't find any such note in the Opus documentation)
- Can I somehow change the
1.3.1 encoderconfigurations, so that it's compatible with a1.1.2 decoder? - Is there a way to install
1.3.1on18.04OR1.1.2on20.04, without manually cloning the git repo and building?

Research direction
No source file, test, or entry point is named. Start by reproducing the distorted audio across the stated Opus and Ubuntu version pairs and compare the manually built v1.1.2 result; done means determining whether the versions are incompatible, whether an encoder configuration restores compatibility, or whether a supported installation path exists.
