Step-by-Step Resolution

Expand each section as needed

1
Symptoms
Info
Recommended validation or troubleshooting step
- Headset works before sleep but Teams cannot detect it after wake. - Microphone appears in OS settings but not in Teams device list. - Replugging headset temporarily restores function.
2
Likely Causes
Info
Recommended validation or troubleshooting step
- USB audio endpoint is not re-enumerated cleanly after sleep/wake. - Teams retains stale audio device reference. - Dock/port power state causes intermittent endpoint availability.
3
Confirm scope, user impact, and reproduction
Info
Recommended validation or troubleshooting step
Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.
4
Validate prerequisites and application/session state
Info
Recommended validation or troubleshooting step
Confirm the user is signed in with the correct corporate account, system time is accurate, network/VPN connectivity is stable, and the application is not running in offline or limited mode.
5
Run safe diagnostics from the Commands section
Info
Recommended validation or troubleshooting step
Use the command snippets below to collect non-destructive diagnostics. Capture output in the ticket when escalation may be required. Avoid deleting profiles, cached credentials, or managed app data unless the runbook or admin approval explicitly allows it.
6
Apply safe remediation steps
Info
Recommended validation or troubleshooting step
- Reconnect headset and relaunch Teams to refresh device enumeration. - Confirm default input/output device in OS and in Teams settings. - Test direct USB connection versus dock path for isolation. - Collect device model and reproducible steps for support escalation.
7
Escalate when access, policy, or security controls are involved
Warning
Review carefully before proceeding
- Issue affects many users with the same headset or dock model. - Driver/firmware update is required and needs admin packaging. - Business-critical meeting workflows are repeatedly disrupted.
Admin review or admin rights may be required for this step.
