Putting the circuit in a metal box that is tied to the signal ground in one place is a good place to start. Simple R-C low pass filters well above the audio frequency but still well below radio helps keep down radio pickup. For example, one R-C pole in the 50-100kHz region won't effect audio, but will attenuate even AM radio.
Minimize Noise in Audio Channels with Smart PCB Layout

Abstract: This application note discusses several factors that affect audio functionality in a cell-phone PCB design. The article shows examples of a problematic and a well-designed PCB for a cell phone. The differences between the two layouts are discussed, with emphasis given to design considerations that improve audio function.

There are no simple do's and donts for PCB layout, each design is different start your design and I will try and help (and its for free on here) (Audio layout is analogue layout, using a DAC means you will have some digital layout. As to PCB experts, you have me as a regular contributor, and I am a PCB expert. I will contribute more later

The simple circuit design needed to amplify an audio signal collected from a system such as a microphone or an audio signal to be sent out across a speaker/Radio handset receiver, etc., is known as an audio amplifier. If you're making an audio amplifier or a Wi-Fi amplifier, your circuit layout must generate and improve the input signal.

Designing the PCB Layout. PCB design also has a major influence on the performance of your amplifier. Below I’ll discuss the guidelines I used to design this PCB layout. The PCB is for a single channel, so for a stereo amplifier, you’ll need to build two boards: Note: The components on the PCB layout match the schematic above.
