-Subject: ALSA: hda - limit internal mic boost for Asus X202E
-
-From: David Henningsson <david.henningsson@canonical.com>
-
-commit 4b527b6516ab1f0af8aaedd02dbf71ee2c1180f4 upstream.
-
-When the input gain for the internal mic is set to its maximum level,
-the background noise becomes so high - and any relevant signal clipped -
-that the setting becomes unusable. It is better to limit the amplification.
