It actually happened since v4.12 as now I get three HDMI LPE Audio devices
show up with 'aplay -l' rather than just one. Only 'device 2' works so if I
change the sink to use that device I get sound. So basically it can be
fixed in userland however I'm seeing others with different devices also
complaining how audio is broken and I think it is something that many users
don't know to fix. Is it worth looking into further or just leaving it as a
known issue?
