In modern systems CPU usage should be negligible regardless of the driver being used, but at least in current Ubuntu (with ALSA and pulseaudio) the player seems more responsive using OSS instead of ALSA, especially when returning from pause. Regarding mixer channels not acting correctly on OSS audio, I think this could be result of a problem in the ALSA driver mixer configuration (not uncommon in HDA codecs). If this is the case, it should happen only with this specific hardware configuration -- in my ALC887 system all mixer channels seem to behave correctly. If you feel this problem is widespread and should be fixed globally, the driver order can be changed in src/main/drivers.c. If it is punctual, affected users can change the default driver in /etc/xmp/xmp.conf and wait for the mixer to be fixed in the ALSA codec driver. Fixing the mixer channels would of course solve the problem for all applications using the OSS API.
