Hello,
I want to record and play a wav file at the same time with the setup (pi + 6mic tool +jbl speaker) so I have to play a modulated sound from the speaker and record that sound from the 6mic tool which is connected to pi. So I am ablt to do that but the wav file that's generated has some hissshhhh kinds sound instead of the recorded expected sound which shoukd be recorded. Can you help me fix this. Don't know it might be issue with the Alsa mixer. @HinTak
