I am also having the problem with my Flip and its .avi files. I did ctrl+i and the audio codec being used is "ms". Any ideas? Thanks.
I'm having the exact same problem with Flip video (VideoLAN detects "XVID" codec), but see 3 different behavior on 3 different XVID files:
1) FLIP XVID AVIs -- PROBLEM
NO SOUND!
VLC detects "Meta-information -- Setting: HAS_INDEX IS_INTERLEAVED TRUST_CKTYPE"
"Audio Device" option is NOT available ("Audio Track" is only "Audio" option)
VLC is way off on the .avi duration, thinking clips are ~10 MINUTES instead of 15 SECONDS
2) XVID -- OK
VLC detects no "Meta-information" (it does not appear as stream info)
"Audio Device" option of Mono or Stereo (default -- no problem)
several other options available "Audio Channel", "Visualizations", "Equalizer"
3) XVID -- Initial problem
No sound initially, by default
VLC detects "Meta-information -- Setting: HAS_INDEX IS_INTERLEAVED"
No "Audio Channel" option, but "Audio Device", "Vis" and "Equ" are available
"Audio Device" is set to "A/52 over S/PDIF" by default (Mono & Stereo are also available)
If I switch "Audio Device" to "Stereo", sound is OK.
*** but for the FLIP videos, there is no way to switch the "Audio Device" to "Stereo".
*** Activating / Deactivating the VLC audio option to "Use S/PDIF when available" makes no difference.
It seems to me that this "A/52 over S/PDIF" setting is getting in the way for FLIP videos, and there's no way to disable it!
