Question

APPLE TV 4k with playbase

Here is the issue in point wise manner:

1:I recently bought sonos playbase, which have only optical audio input.

2: But my TV has regular 02 HDMI and 01 HDMI ARC ports (I don’t want other audio outputs to use be cause of poor audio output quality) and TV has no optical output.

3: I watch content on my TV using Apple TV 4K , which has only single HDMI port as output.

NOTE: I don’t want to use AIR PLAY for SONOS due to audio lag issues.

MY CONCERNS:

1: If I choose a HDMI audio video splitter will it affect my Apple TV video quality.

2: If I choose the splitter should I use it take input from apple TV and then put HDMI output from Splitter to TV and Optical out put to SONOS playbase.

OR

3: I should use Splitter at HDMI ARC as input to splitter and optical out put from splitter to SONOS playbase.

What difference will it make between choosing Option 2 and 3 (of My concerns). Please suggest some good quality splitter also.

SPECIAL MENTION:
I learned that SONOS beam comes with “Sonos Optical Audio Adapter”
to take optical in from TV and provide HDMI ARC at other end to connect to SONOS beam.
I want to ask that if I can use this cable for reverse use like taking HDMI ARC input at one end of this “Sonos Optical Audio Adapter” and plugging other end to SONOS play base.

    Hello

    It seems we have a debate as to whether or not your port is Coaxial or Tos-Link. It's been my experience (and I'm not above being wrong) that labeling for a digital output that is similar to RCA ports has been as follows:

    If Light is involved direct from the source the labeling has been S/PDIF
    If it is Electrical (for lack of a better term) it is labeled Coaxial

    With that said I'd try still try the cable I suggested to see if that works without a converter ($7.99-USD). If not go with Airgetlam's suggestion ($22-USD plus cost applicable cable between it and the TV ).

    Ain't options great! 😎

    Cheers!


    THANKS dear i think, i got the solution, all i need to try these two options ...hope everything works fine. will revert soon.

    hi all,
    sorry for delayed response ... after ordering a digital SPDIF coaxial to digital optical converter i am getting the sound form my playbase...thanks for resolving the issue.

    Though i have lost control over volume levels and i am not able to control volume either through Apple TV4K remote or sing my tv remote , they both are showing tv's inbuilt sound control. however i am controlling the volume from My Play-1s (02 No.) those i have paired as surround speaker to my playbase.
