Cannot access alsa, but yaml has plug and connected after installed

Just created my first snap and now I’m working on trying to get it completely working. The game works, but trying to solve the no audio issue. Here’s my .yaml file:

  fasteroids:
    plugin: dump
    stage-packages:
      - libgl1
      - libglu1-mesa
      - libx11-6
      - libxext6
      - libxrandr2
      - libxxf86vm1
      - libcurl3-gnutls
      - libopenal-dev
    source: fasteroids-amd64-Ubuntu-1.8.2/
    organize:
      "*": bin/
apps:
  fasteroids:
    command: bin/fasteroids
    plugs:
      - x11
      - opengl
      - alsa
      - audio-playback
      - pulseaudio

After installing I ran snap connect fasteroids:alsa but I’m still getting the following errors:

ALSA lib conf.c:3916:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM default
AL lib: (EE) ALCplaybackAlsa_open: Could not open playback device ‘default’: No such file or directory
g_device is (nil)
Error generating sources + buffers

Finding creating a snap really fun, this really is pretty awesome, but still just learning. I did a bit more digging after this initial post and based on Reusable alsa-lib part I reworked my snapcraft.yaml so it looks like:

name: fasteroids
base: core18
version: '1.8.2'
summary: Asteroids remake with more ships and limited controller support

  Fasteroids is an Asteroids remake with adjustable enemy difficulty,
  updated pixelart graphics, and limited game controller support.

I then installed the snap and ran snap connect fasteroids:alsa but still getting:
