a5lte and a5ulte are almost identical hardware-wise, the separate
package is mainly necessary because they use different firmware
signatures.
Alexey Min agreed to do some testing occasionally :)
Make voice call audio work out of the box by starting q6voiced on
all installations with the modem. It might be nice to start it only
when oFono is installed and enabled, but q6voiced is quite minimal
so it does not seem worth the effort.
