Subject: difference between OSS mmap and alsa mmap? [alsa-oss]
Date: Mon, 5 Jul 2004 14:42:51 +0200 [thread overview]
Message-ID: <20040705144251.6a286c94@mango.fruits.de> (raw)
Hi,
the last thing i can see not working correctly in alsa-oss is the mmap emulation [may closed source apps use OSS with mmap emu]. jcdutton told me on irc that this is due to the differences in OSS mmaping and ALSA mmaping and it might not be possible to resolve these issues..
Well, since i don't know anything about mmap'ing device files, i would be glad if somebody could point me to sources of information about mmap'ing device files and especially the differences in handling of ALSA and OSS..
P.S.: the test case here is running Enemy Territory with aoss. Try it and you will see how alsa-oss' mmap emu fails badly [only some craacks and little chunks of audio audible]..
