Distorted audio after waking up from sleep
« on: April 14, 2009, 11:12:13 AM »
As the title says, the audio gets distorted after I wake up my computer from sleep (Fujitsu Siemens laptop with Leopard 10.5.6, and integrated ALC883 sound card), and the only workaround is rebooting the machine. Also, Mic inputs aren't working. Otherwise, all analog outputs seem to work, including headphone autoswitching, which is really nice  :). Thank you to the Voodoo team for your hard work.

I've attached the dump I created with version 0.2.2, in case it helps to identify the problem.

I have the same problem with ALC286. How can I create a dump to verify the problem?

Have you tried to unload and load the kext again after wakeup? This should "fix" it.

I've tried to use kextunload but I've got a "failed" message. Could you tell me what's the correct sintax to unload and load that kext?

TIA,

M.

sudo kextunload .kext

As it says in the Readme it sometimes needs to be executed twice or more times so it will finally unload. Also it could be that it says failed but manages to unload it nearly immediately after, so the next kextunload command will also tell failed because its not loaded anymore. Best is to look in system.log if it finally unloaded, or search for VoodooHDA in the ioregistry.

Unloading twice did the trick, and no more distortions after that.
I'm on a ALC268 too, using the latest version i've lost both mics,while the previous let me use at least the Ext mic
To have the Ext mic in i had to raise the input volume from the "outputs" panel, i forget the name of the item now,
this item is disappeared now in the last version, and i can see only a mic in the "inputs" panel
great work so far btw. thank you

dump included if needed.

I've had a pretty good experience with this driver so far, but like others I too am having distortion on wake from S3 sleep. Hopefully this will get knocked out soon enough. :)

OK, I've did the following:
Code: [Select]
sudo kextunload /System/Library/Extensions/voodoohda.kext
kextunload: unload kext /System/Library/Extensions/voodoohda.kext failed
And after that there is no device available in the pref. pane

But how do I re-load the kext once the command sudo kextload /System/Library/Extensions/voodoohda.kext seems not to work?

do it twice (or triple)
sudo kextunload /System/Library/Extensions/voodoohda.kext
<ignore the error>
sudo kextunload /System/Library/Extensions/voodoohda.kext
then
sudo kextload /System/Library/Extensions/voodoohda.kext
