The kernel configuration change from Debian bug 940726 is invalid, 
according to Intel: https://bugzilla.kernel.org/show_bug.cgi?id=204237#c15

The options for the SST and SOF drivers for Baytrail/Broadwell cannot 
both be set. This will be enforced via Kconfig beginning in Linux 5.5-rc1:

    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=df7257e544faf838c3e7ad6b4e89ffe59e87f5e1

Intel does not consider SOF ready on these platforms yet. 
https://github.com/thesofproject/linux/pull/1382#discussion_r344755772

The following two lines that were just added in 
debian/config/amd64/config need to be removed:

    CONFIG_SND_SOC_SOF_BAYTRAIL_SUPPORT=y
    CONFIG_SND_SOC_SOF_BROADWELL_SUPPORT=y

This is applicable to sid, bullseye, and buster-backports. Thank you.
