Hello, 

 

I have a Sonos Amp which I’d like to connect to my projector via an Amazon Fire stick type device. I wonder what would be the best set-up/method. Any advice would be greatly received. Currently I have it set up thus:

 

Fire stick as HDMI input (Projector has only 1 HDMI input).

Sonos amp (plus bookshelf speakers) connected via Coax through 3.5mm jack in back of projector. (Line in mode)

 

Now this works most of the time when the Sonos app recognises the amp as line in mode. However, frequently the amp decides to switch to ‘TV’ mode and doesn’t play audio. I’m not sure why it decides to switch all of a sudden or how I can prevent it from switching from Line In mode. The projector doesn’t have ARC that I know of, and as mentioned only has one HDMI input, which the Fire Stick is connected into.

 

Is there a way I can stop Sonos switching over to ‘TV’ mode sporadically, or is there a way that I can make the system work that when it does switch to TV I can get audio too? I’ve read about HDMI audio extractors and optical connectors, but I’d not really know where to start with those…

 

Thanks again,

Do you have Autoplay enabled under the Line-In settings for the Amp and TV Autoplay disabled?

Thanks for your quick reply. 

 

Currently the line in is switched to autoplay on the Amp (doesn't seem to be a simply on/off option, but rather select a room), and TV autoplay is off. I have had a fiddle with these settings recently though. Is there a preferred combination for these settings to avoid my issue?

 

Thanks!

Choose the room assigned to the Amp as the Autoplay room and keep TV Autoplay turned off.

Hi, 

Thanks for your help. The settings as described still result in the system changing to TV mode - although this is usually if I change input source (i.e. Switch the HDMI input from fire stick to Nintendo switch for example). I wonder if there is some order of precedence which needs to he adhered to to prevent it changing over. 

 

Thanks,
