I have a TM Nano SE. Audio is fine on all TV channels. However in Radio mode, there is intermittently no sound when selecting certain radio channels. Audio on that channel can only be restored by pressing the Audio button on the remote and switching AC3 downmix from Passthrough to Downmix, then back again or vice versa which then restores the audio until the channel is changed again.
The problem persists on both HDMI and TOSLINK ouptuts. Some radio channels are more prone to this than others. BBC radio channels on 28.2e are particularly a problem. Other stations less so.
I am quite certain the problem is not related to signal strength as SNR is 100%, Signal gain 16.3dB, BER 0
I suspect this is a software bug. Tried rebooting and resetting, but no luck. Problem persists on both Openvix 5.2 & 5.3
Any ideas?
