Please file a different bug. The runtime conflict between SOF and SST drivers has been worked around for now, by making the Kconfig options mutually exclusive. This is still resolved even on Linux 5.5.1 (I'm testing on Arch Linux as well). The issue you are seeing may be related to ALSA userspace or to PulseAudio instead of the kernel; both have been undergoing changes including the conversion to UCM2 profiles, which has unintentionally broken sound in some cases [1]. Please check journalctl for more output.
