Subject: [PATCH] Fix chipmunk-like voice when using Logitech C270 for recording audio.
Date: Sat, 1 Jun 2019 09:52:57 +0200
Message-ID: <20190601075257.GA24550@jimmy.localdomain> (raw)

This patch fixes the chipmunk-like voice that manifets randomly when
using the integrated mic of the Logitech Webcam HD C270.

The issue was solved initially for this device by commit
2394d67e446bf616a0885167d5f0d397bdacfdfc but it was then reintroduced by
e387ef5c47ddeaeaa3cbdc54424cdb7a28dae2c0. This patch is to have the fix
back.
