I now have OSS4 controlling my on-board sound, which means all the mic inputs work properly at last. It also means, if you will forgive the heresy, that the sound quality is much better. This really shocked me, to realise how poorly PulseAudio resamples. The main downside, beyond the initial one of having to get all my applications working properly, is that OSS4 won't suspend nicely. > > That said, I am going to keep using ALSA on my USB audio interface for pro-audio work, because I need Jack and Midi. > > It's not heresy, it's the unfortunate truth for ALSA. I once started reading about Linux drivers and came to the conclusion that ALSA shouldn't have been created in the first place as yet another driver framework - network drivers framework is sufficient enough IMO. There have been a lot of threads on ALSA vs OSS lately - since OSS is now GPL and open source. And most opinions are that ALSA is overdesigned and a manifestation of NIH syndrome. Recent threads mentioning ALSA vs OSS: http://linux.slashdot.org/story/09/09/10/1156218/Linux-Kernel-2631-Released http://linux.slashdot.org/story/09/06/19/1937210/State-of-Sound-Development-On-Linux-Not-So-Sorry-After-All . That said, for me ALSA works, but I choose HW very carefully and stick to SUSE/Novell - the latter _pays_ ALSA developers. Again, that said, to deal with /dev/dsp* is infinitely easier than with raw ALSA, and, as one of the observers in the first thread says, it's the UNIX way.
