What You'll Learn
Pro Tools 12 sound troubleshooting
Pro Tools is a digital audio workstation (DAW) used for music creation and production, sound design, audio post-production, mixing, and other sound-related processes. If you're experiencing issues with Pro Tools 12 and aren't getting any sound output, here are some troubleshooting steps to follow:
Check Your Hardware:
First, ensure that all your hardware components are properly connected, switched on, and turned up. Verify that you're getting audio from other software applications on your computer, such as your web browser or music players. If you can hear audio from other sources, the problem is likely specific to Pro Tools.
Verify Playback Engine and IO Settings:
Access the Pro Tools Playback Engine from the Setup menu and select the correct audio interface you want to use. Check if your interface is set as the playback engine. If not, you won't be able to record or play anything from your Pro Tools session. Resetting your IO settings to default can also help resolve the issue.
MIDI Settings:
If you're trying to send MIDI to a virtual instrument, ensure that MIDI Thru is turned on in the Pro Tools Options menu, and your instrument track is record-enabled. Additionally, make sure your MIDI controller is plugged in, turned on, and properly set up with your system.
Latency and Noise:
Excessive latency or noise can be influenced by the amount of available resources on your computer. A more powerful computer will provide better control over latency. To reduce latency, lower the hardware buffer size from the playback engine settings.
Reinstall Drivers:
Interface issues in Pro Tools can often be resolved by uninstalling and reinstalling the drivers. Ensure you have the correct drivers installed for your MIDI controller as well.
Trash Pro Tools Preference Files:
If the above steps don't work, try trashing the Pro Tools Preference files. This will reset Pro Tools without erasing your work or forcing a reinstall.
For more detailed guidance, you can refer to Pro Tools' official troubleshooting resources and support articles.

Pro Tools 12 and Core Audio
Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology (formerly Digidesign). It is used for music creation and production, sound for picture (sound design, audio post-production and mixing), and sound recording, editing, and mastering processes. Pro Tools can be used as standalone software or with a range of external analog-to-digital converters and PCIe cards with onboard digital signal processors (DSP). The DSP is used to provide additional processing power for real-time effects and to obtain lower-latency audio performance. Pro Tools can also perform the functions of a multitrack tape recorder and a mixing console.
Pro Tools | HD, launched in 2002, replaced the Pro Tools | 24 system and introduced new DSP cards: HD Core and HD Process. These cards offered increased processing power, with HD Core providing 25% more power than the previous MIX Core cards. The HD interfaces supported sample rates of up to 192 kHz or 96 kHz and could be linked together for increased I/O. Pro Tools | HD was designed for OS X and Windows XP and offered a range of new features and a redesigned GUI.
In terms of audio capabilities, Pro Tools supports mixing in surround sound, Dolby Atmos, and VR sound using Ambisonics. It also offers elastic audio, automation, and time code features. The software and audio engine were adapted to 64-bit architecture from version 11, and in 2015, with the release of version 12.0, Avid introduced subscription license models alongside perpetual licenses.
Core Audio is a framework developed by Apple that provides services for audio applications on macOS and iOS. It is a low-level API that offers services such as audio input and output, audio format conversion, and audio mixing and routing. Core Audio drivers are used by Pro Tools to interface with audio hardware and provide stable performance with low latency. The specific Core Audio drivers used depend on the Pro Tools hardware and system configuration. For example, with the Mac G5 system, Digidesign launched PCIe DSP cards that adopted the PCI Express expansion slot architecture.

Pro Tools 12 and HD Omni
Avid's Pro Tools HD Omni is an audio interface that offers significantly better audio fidelity, a wider dynamic range, and super-low jitter. It features sophisticated A/D and D/A conversion and a new analogue front end. The HD OMNI allows users to capture and play back every audio detail, retaining the warmth and presence of the original sources.
The HD OMNI is designed for those who need a small yet high-quality system for mixing, composing, and occasional overdubs. It provides a range of analogue and digital inputs and outputs, including analogue, optical, and electrical digital connectors. However, it is limited to eight channels of audio input and ten independent outputs, including the headphone output.
The HD OMNI offers a persistent mixer feature, allowing users to monitor a keyboard, drum machine, or music player independently from their recording setup. It also includes built-in sample rate conversion on all digital inputs and a soft clip feature to maximize analogue input signals without harsh clipping.
To use the HD OMNI, a connection to an HD card in your computer or the expansion port on another HD interface using a Digilink cable is required. It requires Pro Tools HD 8.1 or later to function.
Some users have reported compatibility issues when using the HD OMNI with Pro Tools 12. While they have purchased the perpetual license for Pro Tools 12, the OMNI HD does not show up in the hardware. Avid has stated that the OMNI HD is not compatible with Pro Tools 12, even with the I/O license. As a workaround, some users have suggested using Waves Digigrid to bypass the need for the HD card and use the OMNI in Pro Tools 12.

Pro Tools 12 and headphone jacks
Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology for Microsoft Windows and macOS. It is used for music creation and production, sound design, audio post-production, mixing, and sound recording, editing, and mastering processes. Pro Tools 12, released in 2015, added a subscription license model in addition to perpetual licenses.
Pro Tools supports mixing in surround sound, Dolby Atmos, and VR sound using Ambisonics. It also supports video editing capabilities, allowing users to import and manipulate 4K and HD video file formats such as DNxHR, DNxHD, and ProRes.
Regarding headphone jacks, it appears that some users have experienced issues with getting audio output through their headphones while using Pro Tools. In such cases, it is recommended to check the Playback Engine settings, as the issue may arise when the Playback Engine changes, causing Pro Tools to switch to the built-in speakers instead of the user's desired interface or headphones.
On a Mac, users can also check their Audio Midi Setup to ensure their headphones are set as the output device. Additionally, it is suggested to ensure that the playback engine in Pro Tools is correctly set up to output to the headphones.
For PC users, one suggestion is to use ASIO4ALL to bypass the interface and directly plug the headphones into the computer.

Pro Tools 12 and sound settings
Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology (formerly Digidesign). It is used for music creation and production, sound design, audio post-production, mixing, and sound recording, editing, and mastering processes. Pro Tools 12, released in 2015, added a subscription license model in addition to perpetual licenses.
Pro Tools supports mixing in surround sound, Dolby Atmos, and VR sound using Ambisonics. It also has video editing capabilities, allowing users to import and manipulate 4K and HD video file formats such as DNxHR, DNxHD, and ProRes.
To configure your audio output in Pro Tools, you need to ensure your interface is selected as the playback engine under the hardware setup menu. You can check if you're getting a signal by creating an audio track and loading a signal generator plugin. If you're using an M-Audio keyboard, you'll need to use an Instrument track instead of a MIDI track to trigger software sounds.
To optimise your Pro Tools preferences, you can enable the "Always Display Marker Colours" option in the Display tab. This colours the areas of the Markers ruler between the markers with alternating colours, helping to delineate song sections. Additionally, the Edit window in Pro Tools serves as the sample editor, and you can use the Zoom Toggle function to quickly get a detailed view of the audio you are editing.
Pro Tools has been criticised for not being as customisable as other DAWs, particularly in terms of keyboard shortcuts and plug-in menus. However, the fixed set of keyboard shortcuts provides a consistent set of keystrokes across all Pro Tools systems.
