Board: based on APQ8016E
Release: Linaro -18.01
We have used a speaker (schematics attached) in our custom board connected to PMIC internal codec.
We feel that the sound quality of the speaker is very low with higher volumes.
We set the volume to “amixer sset ‘RX3 Digital’ 135” and play the sound file and it sounds noisy.
Full command to play a file from speaker:
apply below amixer commands
$ amixer sset ‘RX3 MIX1 INP1’ 'RX1’
$ amixer sset ‘SPK DAC’ on
$ amixer sset ‘RX3 Digital’ 135
play audio file into speaker
$ aplay -D hw:0,1
Is there an analog amplifier for speaker in PMIC that can be configured ? Or the RX3 Digital is the only one ?
Is there any additional speaker related configurations that may help ?
Please help to answer the query.
