**Prerequisites**

- HDMI cable is connected between Arcam SA30 and TV;
- TV brand is Samsung, model UE46F6500;
- TV and Arcam SA30 are switched off.

**Scenario**  
Perform the following steps:

1. switch on Arcam SA30 build 634 version 1.27 is used
2. switch on TV (TV sound will be played through SA30=ok)
3. on the SA30 front panel, go to menu, audio settings, lip sync
4. select ARC
5. change value (SA30 will suppress the TV sound for some seconds=ok)
6. wait until TV sound is played through SA30
7. repeat from step 5 for 5 times, select another value in step 5

**Actual result**  
No TV sound is played through SA30

**Expected result**  
TV sound should be playing through SA30

**Additional information**  
The lip sync settings works as long as the setting isn’t changed more than 5 times in a sequence.
