Hey everyone,

I’ve always been frustrated that Windows doesn’t automatically switch the audio output to my desktop speakers when I place my Astro A50s on their base station. Since Logitech G HUB doesn't offer an official API or option for this, I (me and Gemini) wrote a lightweight PowerShell script to act as a seamless "zero-click" auto-switcher.

How it works: The script quietly hooks into Windows OS events to monitor the settings.db-wal (Write-Ahead Log) file that G HUB uses locally. By intercepting real-time telemetry, it detects exactly when the headset enters or exits the "isCharging": true state.

• Undocked (Lifted): Instantly sets Windows default audio to the Headset.
• Docked (Charging): Instantly routes audio back to your Speakers/Soundbar.

Technical note: I specifically implemented a JSON block-isolation regex. This means if you plug in another Logitech device to charge (like a G502 Lightspeed mouse), the script won't get confused and trigger a false audio switch! I also built it as an event-driven script rather than a polling loop, meaning it sits at literally 0% CPU usage in the background until G HUB writes to the file.

Prerequisites:

• You must be using Logitech G HUB (not the old Astro Command Center).
• Windows PowerShell.
• If this is your first time ever running a PowerShell module installation, a prompt might ask you to install the 'NuGet provider'. Simply press Y and hit Enter to allow it.

Troubleshooting: Script closes immediately or shows a red error?

Windows protects your PC by blocking scripts downloaded from the internet by default. To fix this, follow these steps:

1. Unblock the downloaded file: Right-click the AutoSwitch.ps1 file, select Properties, check the Unblock box at the bottom of the General tab, and click OK. (Alternatively, run Unblock-File -Path .\AutoSwitch.ps1 in PowerShell).
2. Enable local script execution: If the script still doesn't run, your system might have PowerShell scripts completely disabled. Open PowerShell as Administrator, paste this command: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser, press Y to confirm, and try running the script again.

How to set it up:

1. Download the script from Github.
2. Open it in a text editor (like Notepad).
3. Look for the USER CONFIGURATION section at the top.
4. Change $global:SpeakerName to a partial name of your speakers as they appear in Windows (e.g., "Realtek", "Creative", etc.).
5. Save the file as AutoSwitch.ps1.
6. Right-click the file and select Run with PowerShell. (On its first run, it will automatically install the 'AudioDeviceCmdlets' module required to change Windows audio).

Note: This will open a PowerShell window. You must leave this window open (you can minimize it) for the switcher to work. If you close it, the script stops. For a fully invisible experience, use the Task Scheduler method below.

How to run it invisibly on Startup (Task Scheduler)

If you want this to run silently in the background every time you turn on your PC without showing a console window:

1. Open Task Scheduler and click Create Task.
2. General tab: Give it a name (e.g., "Astro AutoSwitch") and select Run only when user is logged on.
3. Triggers tab: Click New -> Begin the task: At log on.
4. Actions tab: Click New -> Action: Start a program.
   • Program/script: powershell.exe
   • Add arguments: -WindowStyle Hidden -ExecutionPolicy Bypass -NoProfile -File "C:\Path\To\Your\AutoSwitch.ps1" (Make sure to update the path!)

Using this with other Logitech Headsets (G Pro X, G935, etc.)

The script is configured for the Astro A50 out of the box, but it should work with almost any wireless Logitech headset (testing needed). You just need to find your specific battery key following this guide or using BatteryKeyFinder.ps1:

1. Press Win + R, paste %LocalAppData%\LGHUB and hit Enter.
2. Open settings.db with Notepad++.
3. Press Ctrl + F and search for "isCharging".
4. Look a few lines above that to find your headset's battery identifier (it will look something like "battery/device_1234/percentage" or "battery/gprox/percentage").
5. Open the script and change $global:BatteryKey = "battery/a50/percentage" to match your specific string.

V1.1 Update: Dual-Switch (Audio & Microphone)

The script now supports switching both Playback (Speakers) and Recording (Microphone) devices simultaneously!

If you use a dedicated external microphone (like a Blue Yeti or QuadCast) alongside your headset, you can enable this feature:

1. Open the script and find the [RECORDING / MICROPHONE INPUT] section.
2. Change $global:SwitchMicrophone = $false to $true.
3. Update $global:ExternalMicName with the name of your standalone microphone.
4. Update $global:HeadsetMicName with your headset's mic name (defaults to "A50 Mic").

The script will now seamlessly route both your audio output and your microphone input when you dock or undock your headset. If you only care about audio output, leave it set to $false and it will ignore your microphones completely.

Disclaimer & Limitations

Please note that I wrote this script primarily for my personal setup.

• Use Case: My daily usage is strictly focused on PC gaming and general audio listening. While the script runs flawlessly for these scenarios, it has not been exhaustively tested across all possible edge cases, complex studio configurations, or multiple audio routing software.
• Windows Only: This script is designed and tested exclusively on Windows. I do not use my headset with any consoles (PlayStation / Xbox). Therefore, I cannot guarantee how the script will behave if your base station is set up in a dual-environment or console mode.

Use it freely, but please understand that your mileage may vary depending on your specific hardware and software environment.

Let me know if you find it useful or if you have any questions.

So, guys, is there any difference between keeping one option enabled versus the other?

Coming from A40, after years and years my headband has finally broke and the ear pads are very worn, so I thought it’s time for an upgrade and I’m liking the look of the A50X.

Found them for a decent price $400 (AUD).

Just a little concerned about the battery life and such.

First time having a wireless headset.

Anyone know a fix? I tried hard resetting the head set and unplugging it

Thinking about getting the Astro A50 Gen 5 and wanted to hear from people who use it

My setup is a macbook, pc, and PS5. Ideally, I want all three connected at the same time so I can switch between them without constantly unplugging stuff

I care a lot about sound quality and mic quality since I use Discord pretty often, and I’ll also be using the headset for work, so comfort matters too

Would the A50 Gen 5 be a good fit for this setup? Also, can I reliably use the PC port for my macbook and xbox usb port for my PC?

Just trying to see how much these would go for? Just found them cleaning out my closet, all three still in great condition with box and all.

Hey all,

I have the Astro A50x (Gen 5 I think? I bought them a little over a year ago but can't remember from where now) and a GIGABYTE - GS32QC - 32" VA Curved Gaming Monitor. I have the charging base plugged directly into my PC but it sits under my monitor (I have the monitor raised on a desk arm). For some reason, when I put the headset on the base station to charge, occasionally, it will cause my monitor to either fully lose connection to my PC (it says "No signal" and swaps to my two outer monitors) OR it will cause severe interference on my main monitor (the image will start cracking and breaking as if my GPU is going bad).

This ONLY occurs when I put the headset on the rest. I've never had it happen any other time and it's random (does not occur all the time but about once a day). Has anyone else had a problem like this? Do you have a solution? If so, what is it 'cause I have NO idea what could be causing this (monitor is wired and both monitor and headset are hardwired into the PC, not run through each other in any way).

how rare are these?
