------- Additional Comments From [EMAIL PROTECTED] 2003-20-09 23:01 ------- I should have remembered my own advice, as in: http://www.mandrakeclub.com/modules.php?op=modload&name=Splatt_Forum&file=viewtopic&topic=8186&forum=1&post_id=25770 Unfortunately I've uninstalled kernel-2.4.22.7mdk and can't find it for download anywhere, so I can't make any further tests with that specific version. Currently sticking to kernel 2.4.21-6mdk (acpi=off) because kernel-2.4.22-10mdk (acpi=off) results in very poor sound quality after some 10 or 20 seconds of live streaming (www.shoutcast.com)... OTOH it is not possible to play sound with alsa after booting with acpi enabled with any of these 2 kernels. That doesn't mean that alsamixer can't be started - it does start without any error messages - but the computer freezes when trying to play any sound through the PCM channel (like "aplay /usr/share/sound/startup.wav"). In summary... KERNEL 2.4.21-6mdk (acpi enabled) Computer freezes at KDE startup sound... KERNEL 2.4.22-10mdk (acpi enabled) Computer freezes at the time KDE startup sound is supposed to start playing... running "chkconfig --del sound" and rebooting allows KDE to load, suspend to disk, and resume...
