That seems like a logical conclusion. The question remains however, which codec is missing? What does MediaInfo tell you about the codec in use?
Hi Harm. Feeling like a total noob here. I downloaded MediaInfo from the web just now, I hope that's what you meant since I'm entering a new anorak world here Here's the read from it:

Well, the source material was HDV, but the material you are using was encoded to BRD format, using 5.1 audio and it not suitable for editing. I would try to get the original footage from the copyright owner.
It is the original footage from my Sony HDR-SR8 camera. And the (not so) funny thing is that I have all of the Sony software installed to!. I guess that media info app is misleading. :/
MediaInfo is accurate -- the source footage from the camera is AVCHD that looks like it's in a M2TS wrapper. The camera records to an internal HDD, so maybe Sony decided on the BD file format because of that.
Check Premiere Pro's preferences for your audio channel mapping settings, check to see that your sequence has at least one 5.1 audio track, and also check Windows audio settings that your sound card is set to downmix multichannel audio to stereo audio (unless you have a 5.1 speaker set up).
I had a similar situation occur recently. What fixed it for me was two things. I had to reactivate Premiere Pro, and I had to clear the cache entirely. The first allowed the codecs to 'reregister", and the second forced PP to create the cache files.
I re-installed AVS4YOU since that was on the list of what I removed. I'm going to clean the cache again (sigh). Un-install it again (sigh). But I'm doubtful since I've done all of that I rekkon a few times by now :/
Un-install it again (sigh).
You don't necessarily have to uninstall. (I didn't.) Just deactivate, shut down PP, reboot, restart PP and reactivate.
I messed about with Premiere's audio settings, including adding a 5.1 channel. Normally when I add a clip it would ask to update the sequence to the new settings and it was all done automagically. I stuck with this process because I was only using one type of file anyway.
Remember the same files play just fine in other applications, windows media player, pinnacle studio 14 HD, Avid Studio (works now) and Sony's Vegas, so messing about with the Windows settings doesn't really add up. Also previoulsy when it worked, when I dragged a clip into the Sequence area there would be a Video and Audio pair, now it'd just video. Also in the Clip view window only the Video icon is enabled, the audio icon is disabled. So premiere just doesn't ackowledge there is sound there.
