How to: ALSA errors on startup or container creation
You may when initialising or booting into a container see errors from the `(qemu)` console of the following form: 
`ALSA lib blahblahblah: (function name) returned error: no such file or directory`. These are more or less expected. As long as you are able to boot into the container and everything is working, no reason to worry about these.
