PreSonus Quantum ES 2: raise a confirmed overly small Windows buffer for pops and clicks
PreSonus Quantum ES 2 — raise a confirmed overly small Windows buffer for pops and clicks. Confirm the actual setup and observed response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Compatible installed Windows Universal Control driver, clicks after buffer reduction.
Connection scope: USB audio. Symptom: Audio keeps cutting out.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is this a supported Windows setup with the Quantum driver already working?
This exact Buffer Size control is Windows-only; do not invent a macOS menu.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Did pops/clicks begin or worsen after selecting a smaller buffer, without an input Clip indication?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-1
Did pops/clicks begin or worsen after selecting a smaller buffer, without an input Clip indication?
A broken USB connection or clipped input is a different issue.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → May recording stop and the old buffer be recorded before changing it?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
May recording stop and the old buffer be recorded before changing it?
A larger buffer increases latency and can interrupt the audio stream.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Choose a larger supported Buffer Size in the Universal Control Start Page
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Choose a larger supported Buffer Size in the Universal Control Start Page
Keep the existing sample rate and project settings unchanged.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Does the same project play with fewer pops or clicks?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
Does the same project play with fewer pops or clicks?
This tests processing headroom, not a promised repair of all dropouts.
Look for: Confirm the stated setup or observation. Unknown stops safely.

Possible result
Checks completed — report what happened
Completion is not an automatic solved result. Report your actual outcome; no Audio Review physical test or measured repair is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Stop and retain the actual observations
A required fact or response was not confirmed. Consult the exact product/partner documentation or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the actual model, source, partner capability and current state before continuing. Do not guess a menu or interrupt a live session/update.
