# Error -9998: Invalid number of channels ## Causes This error occurs if you try to record an unsupported number of channels. ## Fixes Go to Audio Setup -> Recording channels and choose a different number of channels. Values which typically work are 1 (mono), 2 (stereo), and the highest number presented on the list. So for a 8 channel interface, 8 should work. {% hint style="success" %} If the troubleshooting steps aren't working for you, feel free to ask in our communities: * [Forum](https://forum.audacityteam.org/) * [Discord](https://discord.gg/audacity) {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
