Description Need Real Name 2000-10-23 22:43:53 UTC
Whilst an MP3 is playing with the "Scope" visualisation mode selected, the waveform covers only the left-hand half of the scope area. A (stationary) flat line is shown in the right-hand half. Output is to an Opti MAD16 sound card, which is described in /dev/sndstat as: MAD16 WSS (82C930) (DUPLEX) This bug is visible in versions of xmms upto and including 1.2.2, Linux kernels upto and including 2.2.16-3. Sound output via OSS driver.

Have you tried 1.2.3? I can't reproduce this on the cards I've tested on.

I've just had a look at the problem again and have some more info for you: - With downsampling set to 1:1 (44kHz) in the "MPEG Layer 1/2/3 Player 1.2.3 [libmpg123.so]" input plugin, the waveform fills the entire display area, as it is supposed to. - With downsampling set to 1:2 (22kHz) only the left-hand half of the display has a waveform. - With downsampling set to 1:4 (11kHz) only the left-hand quarter of the display has a waveform. I normally use 1:2 (22kHz) for performance reasons. I've not looked at the source, but from the program behaviour it looks as if XMMS is providing a bigger buffer for the waveform data than is actually being filled, leaving the rest as zeros. Yes, the problem is also present in xmms-1.2.3-2 from RawHide.

Ugly hack added in xmms-1.2.4-7.
