Very strange audio issue

So my 2021 Tacoma has been giving me a really strange issue ever since I bought it used back in November. Every time I start the truck I get no sound at all coming from the speakers. The really weird part is, in order to get my sound to come back, I have to blast the heat for 10-20 minutes depending on the outside temperature. The head unit appears to function normally aside from not allowing me to adjust the volume for the first 5 minutes or so as it begins to warm up. I've tried searching through forums for other people having this issue, but I think this issue is exclusive to me. Any ideas are appreciated. Thanks!
