I would like to say I have plain old Sony earbuds, and the sound is very noticeable without playing any sound what so ever. As previously mentioned, upping the dB gain on the headphone mic boost from 0.00 to 10.00 completely stops the hissing for whatever reason.
Also, the Arch Linux wiki has some related notes regarding TLP and hissing through headphones reported. I've not messed with TLP at all. /etc/default/tlp as referenced in the wiki does not exist on my system.
