i have 65’ hisun roku tv that is connected to a Bose speaker via eARC. When i power the tv off, my speaker powers off fine. When i turn tv on, my speaker come one but the sound is frozen and you cannot turn it up or down. Only if i turn the Bose speaker off manually then turn back on it starts working again. After some trouble shooting, i found that the issue is when the option System Standby is selected under CEC setting, when the system powers up, it fails to detect my speaker and the CEC device list says no device detected. If i manually select to refresh the list it finds my speaker and it starts working. I disabled that standby option which leaves my speaker on when i turn the tv off. When i turn it back on, the speaker is already on and it is able to detect and volume works fine. It appears that the CEC device list refreshes on startup before the speaker is powered on and therefore it cannot find it. If the speaker is already on, it finds it with no issue. Seems this could be a bug in how the sequence of this feature happens as it should power all CEC devices first before it attempts to search for them. Any help with this issue? Thank you.
