Is it possible that there's a missing codec on your system? I have a bunch of .avi files which act just the same way. They were encoded on an Edit* system which used a Matrox card, and they will not appear unless you install the codec.
There are several free apps which will give you all the information you need to find the missing codec - I use MediaInfo:
Yes, please let us know the audio codec. Premiere's native AVI support is a bit limited for audio. Unfortunately, when the audio is not supported, there are cases where Premiere will not report this and it will just import as video only.
192 at 48k?
192 is either your bit-rate or your sample rate... Seing as you have the 48k, I'm guessing bit rate, and that you conformed that in AME or another encoder. If they play in VLC and others, you may be looking at a bit-width or file size problem. Check the AVI spec on wikipedia, and make sure your file conforms to normal audio component standards with AVI. It may also be that you are using an audio format that premiere doesn't like. Uncompressed conforms to WAV or PCM standards. You may have better luck re-encoding the files.
Premiere want's 96khz and below for samples, but bit-rate isn't really a consideration unless we're talking WAV files (it won't read non-standard WAV, or anything bigger than 4gb). Your bit-width shouldn't be more than 24bit for smooth conforming, but I've had great luck with files of float 32-bit with audio only outputs to MOV or CAF, which do not have an audio file size limit you'll reach anytime soon.
Make sure you turn on the audio tracks, make sure your playback device is set correctly (AdobeDV is a playback engine that pipes through your machine to your standard audio out, whether that's a device or not it must pipe through your audio drivers first, at least on macs). Also, make sure your audio is not still conforming. If it takes a while, it won't play for a while. I've had the same issue for over an hour when the audio was a huge .MOV. Check the bottom corners of the window for messages about that.
