[SIDDHARTHA NATH]

It was ok previously but it stopped some days back. my tracking results no sound card found.
may be a driver problem or something.
no hardware changes have been made since i started using the device.
lspci -v says there is intel corp. broadwell-U audio controller is there.
please help or advise.
