You mostly tried the wrong model options. According to the diagnostic script your Lenovo has a CX20549. I believe that used to be known as a Conexant 5045 which means according to the HD-Audio-Models.txt file the options to try are laptop-hpsense, laptop-micsense, laptop-hpmicsense, benq, laptop-hp530. This is from that referenced file: Conexant 5045 ============= laptop-hpsense Laptop with HP sense (old model laptop) laptop-micsense Laptop with Mic sense (old model fujitsu) laptop-hpmicsense Laptop with HP and Mic senses benq Benq R55E laptop-hp530 HP 530 laptop test for testing/debugging purpose, almost all controls can be adjusted. Appearing only when compiled with $CONFIG_SND_DEBUG=y Your alsa sound driver version, at version 1.0.21 is old.
