Virtually every program works except skype (http://www.skype.com/) version 1.1.0.13_API. I downloaded the Fedora version of skype from the skype official website. Skype only uses /dev/dsp. I guess skype uses /dev/dsp as microphone input as well. I could not hear anything and the microphone did not work as well if I run skype like aoss /usr/bin/skype. If I run skype without aoss, then skype works just fine. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0001224 artsd-like style ====================================================================== ---------------------------------------------------------------------- nono31 - 01-28-06 06:13 ---------------------------------------------------------------------- Uploaded strace just in case... ---------------------------------------------------------------------- rlrevell - 03-22-06 00:28 ---------------------------------------------------------------------- I am afraid these Skype+aoss problems may be unfixable from the ALSA side. It appears that the Skype binary is self modifying and takes extensive measures to make sure it is not being run in a debugger or emulator. This almost certainly would eliminate any LD_PRELOAD hacks from working. http://www.secdev.org/conf/skype_BHEU06.handout.pdf I believe the only solution to get Skype working with dmix etc. is for the Skype developers to add proper native ALSA support.
