I upgraded my 2.2.5 machine to 2.2.6 and found that sound has is dramatically degraded. Anyone knowing why that could have happened? Whenever playing a midi file I hear some milliseconds of pausing. I bought OSS/FreeBSD (20.00 $) to see if I can quick cure for the problem by using a different driver but it exposes the same problems. I'm using the GUS MAX and never had problems with earlier 2.2.x and sound. Now I'm clueless. -- Chris Christoph P. U. Kukulies kuku@gil.physik.rwth-aachen.de kernel config file included (note that the sound drivers are disabled for the OSS lkms to work). I'm using drq 3 and irq 12 for the GUS. Well, what;s also new is that I'm running isdn4bsd together with upgrading to 2.2.6. # # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file.
