I have connected my audio system to it via optical cable. I can't control the volume with my TV remote and I don't have a remote for my audio system. Please tell me what should I do?</P> Thu, 14 Oct 2021 17:34:28 GMT https://community.sony.sk/t5/android-tv/unable-to-control-the-volume-of-optical-audio-out/m-p/3829844#M56743 Supr.A 2021-10-14T17:34:28Z https://community.sony.sk/t5/android-tv/unable-to-control-the-volume-of-optical-audio-out/m-p/3829861#M56744 <P>It is technically impossible to change the volume via an optical connection being a digital signal and not having an additional protocol to command the external device (i.e. the CEC over HDMI)</P> Thu, 14 Oct 2021 19:03:15 GMT https://community.sony.sk/t5/android-tv/unable-to-control-the-volume-of-optical-audio-out/m-p/3829861#M56744 rooobb 2021-10-14T19:03:15Z https://community.sony.sk/t5/android-tv/unable-to-control-the-volume-of-optical-audio-out/m-p/3830748#M56797 <P>Hey Supr.A, I agree with Rooobb, try the HDMI via Bravia Sync Control.</P> Tue, 19 Oct 2021 14:20:40 GMT https://community.sony.sk/t5/android-tv/unable-to-control-the-volume-of-optical-audio-out/m-p/3830748#M56797 HannahEd01 2021-10-19T14:20:40Z
