Disable HDMI sound output, mouse

Hello,

I have two little problems and I think they doesn't deserve their own thread:

1. When I start my laptop with HDMI cable from my external display plugged in, it is recognized as sound output even the display does not have any.

aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and

aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

works fine.

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

of course doesn't play anything.

It is also taken as primary sound output for every app - chrome (youtube eg.) or vlc... Is there a way how I can disable this behaving? When I boot without HDMI plugged in and then i connected to laptop, everything works fine (primary is my ALC269VC. Only reboots helps.

2. I'm using USB A4 tech mouse :

lsusb

Bus 004 Device 003: ID 8086:0189 Intel Corp. 
Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 003: ID 2232:1018  
Bus 003 Device 004: ID 09da:0080 A4 Tech Co., Ltd 
Bus 003 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

When I boot laptop with USB plugged in, mouse is not responding (even it is recognized by lsusb). I have to plug it out and then plug it in. Then it works.

Thank you for your help

Edit: I deleted problem n. 3
