Final answer:
To specify which I/O settings Pro Tools will use when creating a new session, access the 'I/O Settings' option in the 'Session Parameters' section of the dashboard, and select an I/O setup that matches your audio hardware configuration.
Step-by-step explanation:
When creating a new session in Pro Tools from the dashboard, you can specify the I/O settings that Pro Tools will use by selecting the 'I/O Settings' option. This is usually found in the 'Session Parameters' section of the dashboard. Here you can choose from a list of predefined I/O setups or create your own custom configuration. This setting determines how Pro Tools will handle input and output routing for your audio interface. It's important to select the correct I/O settings to match your audio hardware configuration, as this can affect the ability to record and playback audio correctly within your session.
For example, if your audio interface has multiple inputs and outputs, you would want to configure the I/O settings to reflect the available channels. This ensures that when you create a new track in Pro Tools, it will correspond to the correct physical input or output on your audio interface, permitting seamless recording and mixing.
