They're not that bad, really. I'm not saying they're fine, but they've improved. They don't really have a choice, given that they're a kernel service project now. Basically, you're their client, you're the reason they exist. Just file a bug in bugzilla where you mention that in your specific driver (snd-whatever), mmap() based playback (using glav) in OSS emulation mode seems to corrupt any subsequent audio capture (using lavrec). Also mention that the same procedure works fine on other soundcards. The'll make them treat it rightly. Don't forget: developers can only fix bugs if we know they exist! Ronald -- Ronald S.
