Fix Bluetooth, ASIO, and audio conflicts in Guitar Pro
Bluetooth headphones, a USB interface, an ASIO driver, and a built-in microphone can each work alone yet conflict when Guitar Pro selects a mismatched input and output. Reduce the setup to one output, prove playback, then reconnect devices one at a time.
The practical answer
Select the intended output inside Guitar Pro, use 44.1 kHz, remove an unnecessary input while testing, and increase the buffer for stability before deciding that the score or soundbank is broken.
A step-by-step approach
-
1
Reduce to one output
Quit Guitar Pro, disconnect interfaces and Bluetooth devices, reopen it, and test the built-in output with a simple score.
-
2
Select the device in Guitar Pro
Open Audio/MIDI preferences and deliberately choose the intended output and an appropriate input.
-
3
Match the sample rate
Set the interface or operating-system device to 44.1 kHz and avoid mixed aggregate routes while testing.
-
4
Adjust the buffer
Increase buffer size for crackle or dropouts; reduce it cautiously only when monitoring a live input.
-
5
Reconnect one component
Add the interface, Bluetooth output, microphone, or aggregate route one at a time and record which change recreates the fault.
Start with the smallest working audio path
Quit Guitar Pro, disconnect USB interfaces and hubs, turn off Bluetooth headphones, and reopen a simple score through the computer’s built-in speakers or wired output. If that works, the score and basic playback engine are probably sound; the next goal is to identify the device or route that changes the result.
If built-in playback is also silent, check track and master mutes, install the RSE soundbanks, and follow the broader no-sound path. Do not change notation, reinstall soundbanks, and replace drivers simultaneously, because the result will not identify the cause.
Choose input and output inside Guitar Pro
Open File > Preferences > Audio/MIDI on Windows or Guitar Pro 8 > Preferences > Audio/MIDI on macOS. Select the intended output there even if the operating system already shows the headphones or interface as default. Guitar Pro may retain a previous device across an operating-system handoff.
For distorted Bluetooth playback, official guidance says Windows users should test Audio Input set to None and macOS users should test Built-in Mic. An unnecessary high-quality Bluetooth microphone profile can force a lower-bandwidth two-way mode; removing the input while listening helps keep the output path simple.
Match sample rate and driver ownership
Set the device to 44.1 kHz, the rate specified in Guitar Pro’s official poor-sound guidance. If the interface control panel and Guitar Pro disagree, playback can become distorted, run incorrectly, or fail. Close other DAWs, browsers, meeting apps, or system utilities that may be holding the same device while testing.
On Windows, install the interface manufacturer’s current ASIO driver rather than assuming a generic wrapper is equivalent. On macOS, use the manufacturer’s supported control software where required; many devices use Core Audio without a separate driver. Restart after a driver installation when instructed.
Use buffer size as a stability trade-off
A smaller buffer reduces delay for Guitar Pro’s Line-In or other live monitoring, but asks the computer to process audio more frequently. Crackles, dropouts, or garbled playback often improve with a larger buffer. Change one step at a time and replay the same demanding section.
Bluetooth adds transport latency that a tiny software buffer cannot remove. For tight live monitoring or recording, use a wired output and a suitable interface; for ordinary score listening, prioritise stable playback over the lowest possible latency.
Reconnect devices and report the exact conflict
Reconnect one item, reopen or reselect it in Guitar Pro, and retest. Distinguish failure after waking from sleep, switching from speakers, enabling a microphone, launching a DAW, or changing sample rate. That sequence reveals a handoff or exclusive-access conflict far better than “Bluetooth does not work”.
If the issue persists on current Guitar Pro and current device drivers, give support the operating-system version, Guitar Pro build, interface or headset model, selected input and output, rate, buffer, and reproduction order. A screenshot of Audio/MIDI preferences and a short exported example can make a distortion report actionable.
