[SOLVED] Pulse Audio not working after swapping graphics cards

I'm currently running a KDE Plasma plasma desktop environment, I wanted to do some virtualization with GPU passthrough, so I added a second card and the audio worked fine. There was a problem: Only the first card was being used for GRUB and my BIOS (Any my second card was outputting to my monitors), so I switched the 2 cards around and now my audio doesn't work. (I'm only guessing its related)

One thing I tried that partially worked was deleting /etc/pulse/default.pa, This made Kmix show each individual pactl card (Except for my USB microphone). This made the audio for headphones work! Except then it broke all usage of the pactl command (pa_context_connect() failed connection refused) and it doesn't detect my USB microphone, so I reverted.

Here's my Cards & Sinks.

$ pactl list cards short

0       alsa_card.pci-0000_01_00.1      module-alsa-card.c
1       alsa_card.usb-BLUE_MICROPHONE_Blue_Snowball_201305-00   module-alsa-card.c
2       alsa_card.pci-0000_04_00.1      module-alsa-card.c
3       alsa_card.pci-0000_00_1f.3      module-alsa-card.c
$ pactl list sinks short

0       alsa_output.pci-0000_01_00.1.hdmi-stereo-extra2 module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
1       alsa_output.pci-0000_00_1f.3.analog-stereo      module-alsa-card.c      s16le 2ch 48000Hz       SUSPENDED

I noticed that the analog-stereo was suspended, so I went into /etc/pulse/default.pa and commented out load-module module-suspend-on-idle, still no audio output but it looks like this

0       alsa_output.pci-0000_01_00.1.hdmi-stereo-extra2 module-alsa-card.c      s16le 2ch 44100Hz       IDLE
1       alsa_output.pci-0000_00_1f.3.analog-stereo      module-alsa-card.c      s16le 2ch 44100Hz       RUNNING
