Ubuntu 12.04 sound pops on boot and shutdown, and MIC picks up non-existent static. Edit: please note, Audio out is fine.
Issue
On shut-down and boot I often hear a loud blast from the speakers under 12.04. I was able to get the microphone to work by using the help from "Lenovo Ideapad built-in mic not working in 12.04", and running:
sudo gedit /etc/modprobe.d/alsa-base.conf
and then adding
alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto
followed by rebooting.
This made the microphone able to record, However, there is still a VERY loud background noise/fuzz/static that is recorded by the microphone. This issue is confirmed to not be present under Windows 8 on the same machine (I'm not sure about ubuntu13)
These outputs may have been affected by the fact that I modified /etc/modprobe.d/alsa-base.conf
, I don't know.
$ cat /proc/asound/cards

and
$ lspci | grep -i audio

Probably unrelated background hardware driver info:
I have a Lenovo y410p laptop running Ubuntu 12.04 LTS. I have fixed most of the graphics issues (I get graphical out finally! but I still have to manually change the brightness every boot.), most of the BIOS/UEFI issues, and it triple boots 13.10 and win8. It is up-to-date, and runs the community supported version of Bumblebee to deal with nVidia's lack of direct support for nVidia Optimus products (a reason I might move from CUDA to OpenCL). Not related, but sometimes after the computer has gone to sleep/screen shuts off, and wakes up, the mouse will ONLY move if the left mouse button is pressed -which is a pain (because I can't properly click anything - to save what I'm doing) but fixes itself by logging out and logging back in...
edit: I figure I should put the kernel version and stuff too:

Update
Created 2 new OS partitions for upgrading. Upgraded Linux side from Ubuntu 12 to 14. Upgraded Windows side from 8 to 8.1. Old OS's remain. Still does not work on Ubuntu14.04. Sound is fine in win8.1
