Public bug reported:
zita-ajbridge allows bridging extra alsa devices to jackd as a client.
If that extra device is a USB device and is unplugged, the bridge uses
100% cpu and slows the rest of the system to a crawl. The only way to
stop this process is with a kill -9.
However, there is already a bugfix release upstream. The release notes for
version 0.8.4 (which is already in Groovy) are only one line:
"zita-ajbridge 0.8.4 (05/04/2020)
* Fixed 100% CPU on sound card disconnect.
