Questions and answers
What is needed for a driver? I am having trouble getting sound out of our Altec Lansing ACS90 speakers on our new Dell Win11 computer.
The Altec Lansing ACS90 speakers are designed to connect through a standard audio output, such as a 3.5mm jack, and do not require a specific driver to function. They rely on the audio driver of the computer’s sound card. For a Dell Windows 11 computer, ensure the correct audio driver for the internal sound card is installed and up to date. No separate driver is needed for the ACS90 speakers themselves.
