Hii…
When I try to test my connected USB mic using the command given in the lecture, I get the following error
“arecord: main:788: audio open error: Device or resource busy”
Please help me… I am using a USB mic & 3.5mm speaker is connected to the 3.5mm audio jack.
Pl note that mic is detected by pi.
Also, when I run ps -A nothing else is using my USB mic
Thank You,
Akshay
