I’m getting sound and video from almost everything I’m playing, but one particular movie is resisting me with good video but no sound. I’m using VLC media player and I’ve tried just about every parameter switch I can find. Below are some specifics from this film (from freakyfilms):

Video Codec ...........: XviD 1.0 Beta 2.5
Frame Size ............: 608 x 480
FPS ...................: 23.976
Video Bitrate .........: 1505 kb/s
Bits per Pixel ........: 0.215 bpp
NVOP ..................: []
PVOP BVOP .............: [PVOP] [BVOP]
QPEL GMC: .............: [] []

Audio Codec ...........: 0x2000 (Dolby AC3) AC3
Sample Rate ...........: 48000 Hz
Audio bitrate .........: 256 kb/s [2 channel(s)] CBR audio
Interleave ............: 42 ms
No. of audio streams ..: 1


I see the audio codec is AC3, and I haven’t seen any mention of that in any of the choices in tdh VLC preferences menus. But I’ve tried every choice I can find. No luck.

I’m new at this and I could use some troubleshooting help.

I’ve been checking the VLC messages window...there are a lot of video warnings because I have a slow computer. Here are two audio warnings, can someone interpret them for me?

main debug: audio output is too slow (105182), trashing 85333us

main debug: audio output is starving (172864), playing silence

Audio output is starving, could that be related to a slow computer? Is this AC3 audio codec more demanding than other codecs?

I don’t know if AC3 is much more demanding. One way to check on CPU usage is look at the task manager under performance tab. Is CPU usage at 100% during playback? Is another program running concurrently that’s wasting CPU cycles, which you can close to improve performance?
Also keep in mind AC3 has multiple channels (like 5 or 6 I can’t recall). If you have stereo headphones or speakers you won’t hear everything. There may be an option in VideoLan to convert it to stereo. Media Player Classic does that by default (but the sound is still generally faint compared to, say, MP3; so turning up the volume is often required).

Did you check the separate audio tracks?

Sometimes people have videos with more than one audio track in which one is blank and the other has the audio on it.

Try changing audio tracks while watching the movie.
