Rust and Jack on aarch64

Friends

Are there any Rust programmers here that have had any success with recording or playing audio through Jack on Raspberry Pi?

I am having difficulty with the jack crate in Rust. The system hangs (looking like a deadlock) when the client is deactivated

There are many failing tests in the crate (all hang)

I am struggling with this and am very keen to hear if anyone has made a success of it
