Troubleshooting Steps for Fixing Sound Issues on TM1 Laptops

Method 1: Using Device Manager

1. Right-click the Start button or press Windows + X on your keyboard to open the options menu. Select Device Manager from the list that appears.

2. In Device Manager, expand the “Audio inputs and outputs” category. Right-click on the audio device and choose “Update driver.” Then, select the option to search automatically for drivers. Repeat this step for all devices listed under “Audio inputs and outputs.”


If you don’t find the “Audio inputs and outputs” category in Device Manager, scroll down and expand the “Sound, video, and game controllers” category. Follow the same procedure to update the driver for the ESAuDriver device.

If the above method doesn’t resolve the issue, proceed to the second method.

Method 2: Downloading and Installing TM1 Sound Drivers

1. Click on the following links to download the OEM sound drivers:
ES V2.3
TM1 OEM audio driver

If the downloaded OEM audio driver from this page doesn’t fix the sound issues, you can download the TM1 driver pack and follow the tutorials provided on the page for using the TM1 driver pack.

2. Use WinRAR or a similar program to extract all the files from the downloaded driver package onto your desktop. If you don’t have WinRAR installed, you can download and install it.

3. Open Device Manager again and select the sound device from the list (e.g., ESAuDriver Device for TM1 laptop). Click on “Action” in the menu bar at the top and select “Add driver.”

4. In the dialog box that appears, click “Browse” and navigate to the TM1 OEM audio folder. Select the folder and click “OK.”

5. Click “Next,” and the drivers will be installed successfully.

6. Repeat steps 3 and 4, but this time select the ES V2.3 folder and install the drivers from there as well.

Alternatively, you can install each driver individually. Open the TM1 OEM audio folder, right-click on “IntcAudioBus,” and select “Install.” Repeat this step for “IntcDMic,” “IntcOED,” and “IntcSST.” Then, open the ES V2.3 folder, double-click on “ES AU APO,” and install “ESAudApoEffect” and “ISSTApoExt.”

Note: If you’re using Windows 11, you may need to select “Show more options” after right-clicking each driver file before choosing “Install.”

Restart your laptop after completing the driver installations, and this should resolve the sound problems.
