him Posted December 17, 2006 Share Posted December 17, 2006 (edited) i recently bought an alesis io 2 off ebay and it works great in xp but when in osx 10.4.7 hackintosh the audio is never recognised but the midi function is recognised under the audio and midi setup panel (its an audio and midi usb sound card, the midi shows up but not the audio part) i have other usb devices attached to the computer that all function properly and tried it with all of them removed but still only midi is being recognised i've installed the soundblaster.usb.audio.support.pkg but it seems it hasn't done anything the device is supported by os x and doesn't need any drivers and so far alesis haven't been able to help anybody got any ideas? this is killing me now!

martinleonard Posted March 18, 2008 Share Posted March 18, 2008 got exactly the same problem on leopard - the card is detected in the sound properties but it says it has no output or input controllers so you cant get any sound from any headphones you plug in hopefully someone will post a solution here Link to comment https://www.insanelymac.com/forum/topic/36106-usb-audio-not-working-alesis-io-2/#findComment-672307 Share on other sites More sharing options...
6nikola9 Posted March 19, 2008 Share Posted March 19, 2008 a) download the 10.4.9 combo update MOUNT the 10.4.9 combo update (i.e. double click the dmg file) c) download and launch Pacifist d) choose the package INSIDE the mounted 10.4.9 combo update e) navigate the 10.4.9 combo update file system to: System/Library/Extensions/AppleUSBAudio.kext f) instal the AppleUSBAudio.kext by selecting this and only this kext and choosing Instal (when prompted, allow Pacifist to overwrite existing files). I made a backup of the existing kext just in case. g) quit Pacifist h) download and launch OnyX i) on Startup, allow OnyX to perform verification tests j) choose Cleaning (main menu) k) choose Caches l) in addition to selected items, select System and Kernel caches m) choose Execute n) choose Maintenance (main menu) o) choose Optimize p) choose Complete Optimization (this forces pre-binding) q) choose Execute r) quit OnyX s) shutdown system t) unplug USB Audio device u) startup system v) after startup completes, plug USB Audio device back in Link to comment https://www.insanelymac.com/forum/topic/36106-usb-audio-not-working-alesis-io-2/#findComment-673631 Share on other sites More sharing options...
