Tested on eros q, everything measured from line out,
open circuit.
- volume steps were approximately double the dB they
were labelled as, so "-2 dB" would result in a change
of about -4 dB from maximum (0, +6.2dBV)
- maximum volume defining the line out volume only
changed every 10 values, and then was not close
to correct- "-10 dB" resulted in -2.5 dB from maximum
This gets the volume dB approximately correct, and
maximum volume correctly sets the line out volume.
I was unable to get odd values in the max volume
to work, so set the step size to 2 instead of one.
For "consumer level" (-10dBV), set to -16.
For "Pro level" (+4dBu -> ~1.8dBV), set to -4.

* Track mute state, only call hw if actual change is needed
* Don't unmute in audiohw_postinit()
* sample rate tracking fixes
* erosq: Don't start up muted

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?
