Hi All,

  I have situation where I need to reset the sample rate depending on
the incoming settings.

How can I do it ?  I have tried below ways.

I found changing a2dp_sbc_t sbc_presets[1] frequency from  44100 to
48000 in hal-audio-sbc.c, will change the device sampling rate, but
only once.

In order to achieve changing sampling rate dynamically, i used the
below methods. Both did not work

a. stream_out->common.set_sample_rate(&stream_out->common)
b. stream_out->common.set_parameters(&stream_out->common","sampling_rate=48000");

Has anyone tried changing audio sample rate dynamically? If so, please
share how it was done?

Advanced Thanks,
Prabhu Chawandi
