How you getting past the studs/noggings? Don't run with ac cabling.
As far as performance is concerned, it’s not a problem.
Many old cinemas my predecessors built were perfect. The odd one, something went horribly wrong and ac lighting cables and speaker cables were inside the same cable trays for many many meters with no separation, in the equipment room. Lights were controlled by triac based dimmers, so electronically very noisy. Between 5-10 meters of cables practically touching each other, and super high sensitivity speakers connected at the end of the speaker cable (98-110db 1w 1m), it’s a much worse case then a residential walls vertical run of 2.6-3m with consumer based 87-92db 1w 1m speakers. The impedance of the speaker is 3-8 ohms nominal, the induced voltage is too low. I’ve seen 30-40 meters of speaker cable zip tied to lighting cable barely cause any noise.
AS/NZS3000:2018 has something to say, but anyone installing speaker cables after AC cables are installed, isn’t breaking rules.
I would strong discourage of course. Separation is wise. Think if a rat chews through cables, 230vac ends up on the wall plates binding posts, kid touches the binding post, and the ac circuit isn’t RCD protected.
Typically a wood framed house has one row of noggins in the frame. You can drill the top plate and with a super long bit drill the noggin if it’s a concrete slab building.
If brick veneer, wood sub floor and single story, lift some roof tiles and use yellow tongue to pull the the cable down or up the gap between frame and bricks. (You’ll curse a brickie who’s let too much mortar ooze into the gap), then run under the floor to your locations, drill up and out your hole for wall plate(s).
