So originally, I was trying to get my audio interface to work on my ubuntu system on FL studio, I was looking for lower latency audio asios and I heard about jackd2. Being a noob, knowing I had pulseaudio already installed, I went ahead and downloaded jackd2. My computer no longer can detected my headphone jack, and is routing all audio through my laptop speakers. I installed Cadence and Jackd2 again after uninstalling it to see if I could get pulse to integrate, which was unsuccessful. Here is Jackd's error log in cadence.

**If anyone could give me a lead to fix this problem and get my headphone/audio drivers working or how to set it back to just pulseaudio I would really appreciate it. Thanks for the read!**
