Yes, I have the same settings (for HDMI). Note that my yamaha rxa 2010 is working properly with my TV and my Samsung TV model is quite common and not an old model. I know that wiim is trying to solve the issue and if I understand correctly it has managed to make it work for many different tv models. It is just that they have not managed to make it work for all TV models. Berhaps a hardware restriction? I disconnected the hdmi cable because I cannot have my TV muted for half a minute every time I switch on my TV.

The CEC is turned off by the WiiM, so if the TV tries to connect anyway it's a issue with the ARC settings for the TV. I really don't see what WiiM can do more, as the TV connot connect ARC when CEC is off.

You say that the TV don't try to connect if the cable is disconnected? If so, then the TV somehow can detect the presence of the WiiM without a CEC signal. That is strange.

Yes I do believe that wiim is disabling cec but my TV is using a different way to detect wiim presence, at least for a few seconds. I run some more experiments before giving up. My TV has some hdmi ports that are not arc enabled. If I connect wiim to a non arc-enabled hdmi port of my TV, then when I open my TV, the TV complains that I am using an HDMI port that is not arc-enabled. So my TV does detect the HDMI cable connection to wiim and identifies the fact that wiim is not outputing video. Therefore it urges me to use a port that is arc enabled. So my theory is that Samsung identifies that (a) an hdmi cable is connected to an external device(aka wiim), (b) identifies that wiim is not outputing video therefore is must be an arc device, (c) switches to external speakers mode for a few seconds until an arc time out is triggered and then returns to internal speakers more. Just my guess...
