Importing AVCHD files to Davinci Resolve 12.5 with No Audio?

Dear all, I have downloaded the free version of DaVinci Resolve 12.5 for the first time, and I am trying to learn how to use it . But I have some questions:
- I. imported AVCHD files ( MTS files ) from Panasonic AG-AC160 but I did not see the audio clips or there are no audio clips in the timeline, only video clips are available in timeline without audio clips Why????? ?
2- Other video not ( mts files ) appeared both audio and video clips ? but How could we see both audio clips I mean sometimes I record audio of surrounding using the internal microphone and also using wireless sennhiser on the other channel and I need to see both for edit in DaVinci Resolve 12.5 so how could I see both stereo audio channels in timeline ?

AVCHD audio specification

AVCHD audio can be recorded in 5.1-channel surround sound with Dolby Digital (AC-3) compression or up to 7.1-channel surround sound (uncompressed). Some cameras, such as the Panasonic HDC-SD5, use a two-channel built-in microphone. If there is no audio when importing AVCHD to Davinci Resolve, the main reason is that Davinci Resolve fails to handle the 5.1 channel AC3 & DTS codec or 7.1 channel Dolby TrueHD or DTS-HD Master audio in AVCHD video, therefore, to fix Davinci Resolve importing AVCHD no audio issue, you will need to transcode the unsupported AC3, DTS, Dolby TrueHD or DTS-HD audio to Davinci Resolve handle audio codec such as AAC or MP3. However, a codec transcoding process can sometimes result in a lack of surround sound.

Transcode AVCHD for Davinci Resolve with Surround Sound preserved
