I have a number of audio anomalies with the Premiere that are on the same feed and same switch and same A/V receiver as an S3 and HDXL that DON'T have any audio anomalies. Some of the frustration audio problems of the Premiere:
1. Your "stuttering" problem: audio present for a few seconds, then gone for a few seconds, then back a few seconds, then gone a few seconds, but not a "machine gun" rapid stutter, if that is what you mean? I have to switch the A/V to another input and then back. This fixes is 98% of the time.
2. OUT OF PHASE AUDIO: This happens when all is well and right after a random Skip Back or Skip Forward command. The fix is to either Skip Back or Skip Forward to resume in phase audio. This problem is FREQUENT and occurs about every 1 out of ten or FEWER skip commands.
3. Sometimes the audio seems to fade to a lower level, than return to full level, then fade again and might stay in the fade for quite a long time. I have either leave the recording or channel as what is viewed--changing to some other channel or recording--then go back to the original channel or recording and that usually fixes the problem.
NONE of these problems exist on TWO S3 platform TiVo's hooked up the same way to the same TV and through the same switch and A/V receiver. This is a PREMIERE problem. TiVo, please fix.
