Soundproblem after update from Version 0.8.2 to any newer

[b-star]

Hi,

I use VLC for SVCD.
Everytime I try to update VLC to any newer version than 0.8.2, the sound makes strange noise so its not possible to watch the movie without headage.

I tried every update, but i ever had to return to version 0.8.2.
I don't think its a bug, otherwise the other users would have the same problem.

Maybe it's my Hardware:

Dell 8250
Pentium 4 3,066 Ghz
512 MB RAM
Creative Audigy 2 ZS (Soundcard on PCI; Original, not from Dell)

Summary:
Version 0.8.2 --> no problem
Version any higher --> sound problems

Could anybody tell me why?
I don't understand this.

greetings b-star

The DirectX module was rebuilt starting with 0.8.4 to be more compatible with DirectX 9c. If you have Windows XP SP2 or DirectX 9c installed you will probably need to update your video and or sound drivers.

The only known problem is with VCDs or KVCDs where the work around is to play the .dat file directly. Or in the case of a image file use an emulator or burn the image to disk and play the .dat file.

Hi,

I have got the same problem with SVCD and Audio - my config is
- Windows XP SP1
- Audio out via Win32 Interface (not directX - because there was an older problem when playing DVD oder MPG2 - where the audiostream floated away after fast forward... ?)
- the SVCD is stored as ISO and mounted with Daemon Tools

Playback of DVD, DivX, MPG2 files - works perfect on the same computer, only SVCD produces where bad sound?

VLC is a stand alone player that uses its own libraries to decode media files it does not use Direct Show. So there will be no interference between VLC and another DVD or media player.

The things that they do have in common is DirectX and the operating system. If you are using VLC 0.8.4 or later, the DirectX module was rebuilt to be more compatible with 9c and some users have needed to update there video card's drivers and or sound drivers after installing SP2 or DirectX 9c

In almost every case where the user has not updated to SP2, the user is experiencing problems with third party media players. So it may be best if you intend to be a hold out on SP2, you may want to revert to VLC 0.8.2 and dump your new player.

that sounds not so good - the funny thing is - that playback of DVD / DivX and plain Mpeg2 Videofiles works with VLC -- only SVCD audio playback is junky --- so it sounds not so logical to me upgrading drivers or servicepacks would help?

Seems that the last time I looked SVCD was MPEG 2. As I also recall the original specification was 480x480 and did not display well on most monitors until the specification was updated. I included the generic answer because the only people having problems seem to be the hold outs and of these VLC 0.8.2 seems to work fine for them.

I have tried many SVCDs and have yet to experience the problem, but I have noted the problem of KVCD and or VCD that there is a ticket on. Hopefully this will be resolved in future releases but for the moment there is a work around for this problem.

You could try shutting of the "Skip frames" option in Preferences, Video and see if this helps. Although the problem to me sounds like a audio card driver problem. You could also try shutting down DirectX for audio in Preferences by choosing the "Win32 waveOut extensions output"

Noise for some audio cards occurred when the drivers and or card did not support the float32 option and may be changed in Preferences, Audio, Output modules, DirectX. Of coarse this will require DirectX to be set on or the default.
