Janusromanus Posted November 29, 2007 Share Posted November 29, 2007 Hi there from spain, i usually use the tubgilr 10.4.8, all working fine, but i recently updated the bios to the latest version and sound goes off, for some reason even the device and vendor (obiously) are the same the osx don´t load the sound, i tried some kexts but nothing happens, the asus bios applications don´t let me downgrade the bios, any ideas to make sound work again would be apreciated. Thanks in advance. Alex Link to comment https://www.insanelymac.com/forum/topic/73965-update-bios-no-alc850-sound-in-1048-or-10410/ Share on other sites More sharing options...
Janusromanus Posted November 29, 2007 Author Share Posted November 29, 2007 Solved!!, i downgrade my bios version to 1.09 (i think is the next downstairs 1.303), and all goes well, sound in 6 channels...etc, some problems with macos and rebooting with sata solved too. For downgrade i have had to use AWDflash 1.07 because the 1.09 and above (including asus update 6 and 7) don´t let me downgrade to a previous version of the bios. Alex P.D.: I don´t understand why a bios update make OSx don´t see the soundcard... who knows..., ehm have 5.1 sound but only the first two channels sliders in audio options are avaliable.
