I checked the mixer configuration.The registers 0x18h
and 0x04h were mute at the time of initiating DMA for playback.
I did set both registers with 0x7fff. From mixer point
of view, If I am using an headphone, are these registers enough? I am still not able to hear anything.
Please provide alsactl output as requested - any configuration should be done via the ALSA mixer rather than register writes. In the case of register 0x18 setting 0x7fff will set a gain of -34.5dB on each channel which may be too low, depending on your input.
Here is the mixer-config file got through 'alsactl'. Could you please guide me which controls to set with what values using amixer, for playback through Headphone and Recording?
