I'm looking into the Audio issue ASAP. If someone could confirm: This was fine on the previous builds, right?
I can't say because I'm still using cr-6.1 as my daily driver, but AFAIR there haven't been complaints about changing audio volume etc. in older cr-7.0 builds both here and on your Z3 cr-7.0 thread.
Other issues which keep me from using cr-7.0 as my daily driver yet are:
- Notification LED is not working yet and charging LED is very dim.
- Sony Stock Camera and Sony Album can't access SD card yet for saving and deleting pictures.
