Regression: No sound when playing WMA9 Pro (and others audio format) since 2.0.6 update

Since the VLC-player upgrade to version 2.0.6 on my Mac (and on Windows) there is no sound when playing wmv-files.

• WMA9 Pro and WMA10 Pro and both affected but WMA9 Pro gives no sound at all while WMA10 Pro stutters. Although some WMA10 Pro files are playing fine.

But some other audio formats are also affected:

• MPEG-4 ALS
• Monkey's Audio APE, was half broken in v2.0.5 but now it's completly broken
• MLP
• AIF with ADPCM-IMA4

This is very likely due to the libavcodec update and the WMA2 change...

If you mean 2ff3b97b, it has nothing to with this problem, the code that this commit changed has now been removed completely.

BTW luckynight.aif works fine for me on vlc.git, all others are broken

luckynight-als.mp4 and lickynight.mlp are different problems.

All the others play fine if you disable audio synchronization by making TimeGet() return -1 in your audio output.

Why are they broken in 2.0.6 then?

Last time I checked the demux seemed to send packets to the decoder in bursts rather than continuously, thus triggering synchronization.

You can check that the decoder works fine with --aout file --audiofile-file out.wav
