Hey @rgilkes, welcome to the community.
I’m going to assume that your studio monitors are active (powered) speakers with multiple inputs such as 1/4” and RCA jacks. If you’re looking to play from your studio monitors and your Sonos speakers at the same time without delay then unfortunately that wouldn’t be possible. You could hook up a Sonos Port to the back of the monitors as either an audio source by connecting from the Port’s line out jacks, or, if your monitors have RCA out, you could send that audio to the Port’s line in jacks to send that audio to the rest of your Sonos speakers. Though if you’re going the line-in route, you would be subject to that 75ms delay.
If you’re looking to use a Sonos product as PC speakers, I’ve written an article on how to achieve this.
If I haven’t understood what you're looking for then please let me know, perhaps with an example use case. Model numbers of the kit you're looking to hook up would be beneficial too 
Are there any devices that can take two audio inputs (computer audio & Sonos amp/port input) and switch between the two, preferably automatically. Bonus points if I can also switch the output from the studio monitors to headphones on the fly.
Audioengine. (They don’t switch, they simultaneously accept two inputs.)
I’ve used the little A2s on my desk for years, with input from the computer and Sonos (ZP80, then Port).
Hi @James L.
Thanks for the response. I’m not looking to group pc speakers and Sonos speakers, I’m looking to use one set of studio monitors and switch between two inputs (input 1: computer audio, input 2: Sonos amp/port). Hope that helps. I don’t have an equipment list yet, as that’s what I was hoping to get suggestions on through this thread.
@ratty Thank you for the Audioengine recommendation. Since you can’t switch, does one input just take priority over the other when it has a signal?

No, they’re both active. There’s an internal mixer.

Oh ok. I think that is fine. Taking look at their speaker lineup and the HD3’s look like they may be just what I need with the added headphone output.
One operational question for you. In terms of volume control, do you find yourself leaving the speaker at a certain level and then adjusting volume through Sonos or do you do all volume control on the speaker?
I never touch the speaker’s own volume (which is round the back on mine). Set and forgotten.
The Sonos level is adjusted via the Windows controller; the PC level is tweaked (if necessary) on the desktop, though of course the likes of YouTube also have their own volume control.
By the way there could well be other makes of desktop monitor which provide in-built mixing, but Audioengine have served me well.

Thanks again. These look like a perfect option!
