With ALSA, there are no convenience wrappers or abstractions. It is currently the recommended way to use Ardour in production. Why does it matter though Your audio device probably doesn’t report the true input or output latency. On Linux, you have multiple audio systems (or backends) available. Available in Window->Audio/Midi Setup/Calibrate, this physically measures the round-trip latency of your audio device. My set up is Gentoo Linux with the Pro-Audio Overlay running Ardour for. At the next step, you will need to choose and configure the audio system. Ive just begun setting up my studio to use a computer for more than MIDI sequencing. Then, if possible, plan to sell or donate your USB mic, get a proper audio interface and an analog microphone. Choosing an audio system and its settings. You should use the latest version of Ardour (6.5), Use the ALSA backend. You should almost certainly NOT be using JACK if you are new to Ardour. The only way to know this is to know that NVidia is a company that makes this type of hardware. The HDA NVidia device is associated with your graphics/video card, and won’t be correct unless you plan to use the audio built into HDMI-connected monitors/screens. So this device is the builtin audio for your computer, and if you’re just going to plugin to the jacks/outputs of the computer, it’s the one to use. The device often shows up on Linux with a name that includes the word “PCH”. “Intel HDA” is the name of the so-called standard for the builtin audio interface (“soundcard”) inside most computers. ![]() OK, lecture over, because you don’t currently have that option. The correct setup is a single audio interface that performs analog->digital conversion from an analog microphone, and digital->analog conversion going to your speakers/headphones. Change audio device setup of existing session Getting Stuff Done How do I. While this does work, it’s a suboptimal way to work. The makers of these devices are relying on the idea that software, somewhere, will “fix” this problem by doing what is called “resampling” to keep the input (from your mic) and output (to speakers/headphones) in sync with each other. ![]() There is no way for your USB microphone to use anothe device’s sample clock. There is no way for your USB microphone to share its own sample clock with anything else. The first rule of digital audio is that everywhere that converts between analog and digital signals should use the same sample clock. As I keep saying over and over, it is really unfortunate that the manufacturers of these devices have convinced so many people that these are the devices they should buy, when in fact they are fundamentally a bad idea. I hate to be a bore, but the first thing to say here is that you should not be using a USB microphone at all. Unfortunately, the initial news is not good …
