I have been a photographer (sole proprietorship) for about 6 years now. Recently, I have been doing some video and audio editing. Does the IRS see me as having two separate businesses now? Or can I update my business details with the IRS and state so that I won't need two Schedule Cs, two records of accounting (income and expenses), etc.?
As long as your work is still generally in the same industry or profession, then you can still file it as a single Schedule C. You might update your business code used with the Schedule C if there is a better fit for what you do.
If you had remained a photographer and decided to start making crafts or doing bookkeeping, then you had clearly started a new, second business.

would the same be true of state gross receipt (sales) taxes?
Probably, but you should confirm that with your state to be sure. That question is not within the scope of something we can answer here.
