Compile error: playback/src/mixer/softmixer.rs:1:25 unresolved import `std::sync::atomic::AtomicU64`

[pejobo]

Describe the bug I use the docker image for cross compile (with the change described in #994) and get a compile error (see below). To reproduce Steps to reproduce the behavior:

1. Follow cross compile description in wiki, but patch Dockerfile to use debian:bullseye
2. See error

I don’t know, I don’t use docker. Doesn’t it support 64-bit atomic? What is the host platform? And which Rust version does it run?

[pejobo]

The container sources rust from https://sh.rustup.rs, see https://github.com/librespot-org/librespot/blob/dev/contrib/Dockerfile#L29 So I assume it's the latest stable rust version.

Host platform is Debian bullseye (this is my modification to the Dockerfile linked above, see #994 for the reasons for this change).

[pejobo]

Sorry, I rebuild the container and the problem vanished. Closing.
