osssink output is distorted when TPB (Thinkpad Buttons) is running. TPB
is a program that polls /dev/nvram for changes when using extra builtin
buttons on IBM Thinkpads.
If I set TPB to a longer polling period, the distortion is minimized, although it doesn't disappear. This only occurs with osssink and not alsasink or esdsink.
Is this a bug?
this bug?
If it only happens with GStreamer/OSS combo and not with other OSS using
apps and if it happens on any kernel, it's pretty likely that we're at
fault. It doesn't hurt to file this as a bug in our bugzilla though I
don't think anybody from the GStreamer team has a Thinkpad so it's not
very likely that we can do something about it.

I did some more testing on this problem. It only appears with the GStreamer/OSS combo when using the cs46xx Alsa driver with OSS emulation. Specifically, it only occurs on the "New DSP support" option. The new DSP enables SPDIF and dual codecs but I only use it for the hardware mixer.
I tested using the old DSP and OSS drivers and the problem did not
appear. No other OSS applications cause the problems using the New DSP either.
