Hi,
I have a question about BT_VOL_CONFIG parameters.
The Melody manual states;
BT_VOL_CONFIG = (def_hfp) (def_a2dp) (a2dp_steps) (volume_scaling_method)
where;
volume_scaling_method:
- Hardware: volume scaling is applied at the DAC in the case of analog output.
- DSP: volume scaling is applied in the digital domain by the DSP.
When I set <volume_scaling_method> to 2, it returns an error 0x13 meaning wrong parameter.
Could the manual be wrong?
What are the correct options:-
0. Hardware: volume scaling is applied at the DAC in the case of analog output.
- DSP: volume scaling is applied in the digital domain by the DSP.
or - Hardware: volume scaling is applied at the DAC in the case of analog output.
- DSP: volume scaling is applied in the digital domain by the DSP.
?
Thanks,
Keith
