Public bug reported: In GCP images it is possible to create virtual MIDI devices and generally do stuff like audio routing, etc.
At CircleCI, where we run many of our VMs on Ubuntu in GCP, several of our customers use this functionality to test audio equipment in their CI runs. Unfortunately they cannot run their tests on our AWS based VMs, as there is no sound support compiled into the kernel on the AWS kernel and images. See the package listings for the other kernels for, e.g. the loopback driver: ``` linux-modules-extra-5.4.0-99-generic: /lib/modules/5.4.0-99-generic/kernel/sound/drivers/snd-aloop.ko linux-modules-extra-5.8.0-1031-oracle: /lib/modules/5.8.0-1031-oracle/kernel/sound/drivers/snd-aloop.ko linux-modules-extra-5.8.0-1032-gcp: /lib/modules/5.8.0-1032-gcp/kernel/sound/drivers/snd-aloop.ko ``` We would love to be able to install the sound drivers (especially snd- aloop) with the linux-modules-extra-aws package, but currently cannot, and obviously do not want to start running our own kernels, as then we lose the immediacy of kernel patches provided upstream by Canonical.
