Question about nrf_drv_pwm_simple_playback based thingy52

[victor_CHINA]

I am build a sound client project

when I received the data from the thingy52（which is sound server device）

the I play the sound by function drv_speaker_ble_pcm_play directly without use the drv_speaker_tone_start function

the result has so much noise that I cannot hear the sounds

QUESTION

1、I think follows may be wrong

a、I must use the drv_speaker_tone_start before drv_speaker_ble_pcm_play

b、the sound data from another thingy52 is 8bit 8khz，while the function drv_speaker_ble_pcm_play is used for play 16bit 8khz data

which is right？

This case is related to your other question, right? Is it correct that you want to stream music from a Thingy:52 to a nrf52dk?

[victor_CHINA]

yes that is what I want。 it is the same question

but I donot why It sound noise

[Bjørn Kvaale]

Have you tried using the drv_speaker_tone_start function before the drv_speaker_ble_pcm_play? Is the sound quality any better then? I would try that first and see if it helps.
