Hi Clemens,
Can I directly stream the recorded data as playback without going for any conversion or anything to the captured data?
I am hearing pure noise if I am streaming back directly the recorded sound that I captured. Is this an expected behaviour?
Really appreciate any advice.
Thanks,
grace

Hi,Do you know of any means how to test the streaming IN raw data. I am attaching a headset and could only test the speaker or streaming OUT. I need to test as well the streaming IN.I am writing every single byte I received into a buffer, and after some period, I am streaming it out again, but I can only hear noise and no clarity in the quality of the audio captured.My captured settings are as follows:Sampling Freq = 48000Channel = 1Sampling Bit = 16when i streamed it out, the playback settings are as follows:Sampling Freq = 48000Channel = 2Sampling Bit = 16I forcefully change the channel number to 2, would this cause any problem?Any advise can be deeply appreciated.Thanks.regards,Grace

ALSA will allow only those sample rates/formats that the driver says it
supports (in the snd_pcm_hardware structure, and with any constraints
set in the open callback).
