+From: Takashi Iwai <tiwai@suse.de>
+Subject: ALSA: Fix sample rate of Lenovo Ideapad to 44.1kHz
+Patch-mainline: 
+References: bnc#480391
+
+Noises can be heard on analog outputs of (some model of) Lenovo
+Ideapad due to the hardware problem, and the only workaround right now
+is to fix the sample rate to 44.1kHz.
