cannot drag audio to timeline

[senderj]

I am using old CC2015 PPro. I import a few clips with mixed resolution (1920X1080, 1280X720) all h264 in mp4 and all with AAC 2ch audio but mixed sampling (44.1k, 48k). When I drag one into timeline to create a sequence, it works well. But when I drag a second clips to the timeline, only the video track can be put into the sequence, audio track cannot. This happens doesn't matter which one I drag first. And it happens even if the clips has same video resolution and same audio sampling. First one always ok second one always video only. The only way to get all trackes into timeline is to drag all import together. I don't know if I messed up with the setting or something else. I have been using the software for so many years and I didn't have this problem before. Please can somebody help me.

It's Track targeting. Look to the left end of the Timeline panel controls. You'll see a blue box on the video track that your clips are on.

But apparently there's no audio track selected  with a blue box below it. So no audio is brought to the Timeline.

Click an audio track box below the blue video track box. When it turns blue you can add audio there.
