OSS is dying in mainline, distributions are desupporting it and it's just painful all round to carry the bodges for it in kernel, so I really would recommend exploring the userspace solutions if you need to interoperate with this unfixable userspace stuff. I'd anticipate you will run into further issues going forward with kernel side changes, and it gives you more room to do things like soft mixing in your userspace stack too. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
