I am trying to amplify a 0.4Vpp audio signal to 1Vpp using OPA344 however my output is clipping around 0.5 volts even though my supply is 3.3v

Op-amp is in inverting configuration: enter image description here

blue trace is input, yellow is output. enter image description here

[UPDATE] Fixed - However I'm considering putting the voltage divider on the output so changing the gain won't change the bias

Updated the schematic, this puts me at 1Vpp with a 500mv bias: enter image description here

Op Amp clipping signal way below rail
