No HDMI output on your TV? No problem! Simply snag one of these Optical Audio Adapters from Sonos and Sweetwater. This 4.5-inch adapter sports a TOSlink optical connector for plugging into your TV's optical audio output and an HDMI Type-A port for connecting to your Sonos Beam or Arc soundbar with a standard HDMI cable (sold separately). This means that you can experience Sonos Beam or Arc soundbar audio quality even if your TV doesn't have an HDMI output.

Sonos: pioneers of wireless multiroom audio

True pioneers in the field of audio technology, Sonos has completely revolutionized home listening by perfecting the concept of — and implementation of — wireless multiroom audio. Since its founding in 2002 by four music-loving engineers in Santa Barbara, Sonos has continued to innovate with a state-of-the-art stable of wireless speakers, home theater systems, headphones, and architectural audio solutions. Backed by thousands of patents and guided by a team of Oscar- and Grammy-winning sound experts, Sonos delivers sound exactly as the artists intend: immersive, detailed, and emotional. Moreover, much like Sweetwater, Sonos cultivates a culture of creativity, inclusion, and sustainability, remaining committed to shaping the future of audio experiences worldwide.

Sonos Optical Audio Adapter Features:

  • Adapter for using Sonos Beam or Arc soundbars with TVs that don't have an HDMI output
  • TOSlink optical connector to HDMI Type-A port
  • Connect via any standard HDMI cable (sold separately)

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
