That's the best bet. Mike is great.Originally Posted by skippy911
As far as the sound. Mine would forget about having something plugged in every time it went to sleep/booted. Since I moved it to the headphone port on my Sonica Theater I haven't have any issues. Now if they would just put out an Intel driver for is so I can actually use it for it's intended purpose
I know what your going through cause i had the same problem of low volume and noise while installing an intel mini in a friends car, he was also using the aux in on his factory radio. We tried to solve the low volume problem by getting a line driver to up the voltage going to HU, but it seems his factory radio could not hadle the 5volt output of the line driver and turnned off everytime the volume was turned up high. The combination of the noise and not being able to hear his music while driving with his window down drove him crazy and he ripped the whole system out his car a couple of days later. Eventually i convinced him to install an aftermarket amp and all the problems seemed to vanish.Originally Posted by skippy911
Ok I resolved two issues but a new one has sprung up, will it ever end!!!!!!? Ok, I plugged the ignition on cable into the rear cigarette lighter socket and let the mini goto sleep, for about 3 hours, went back and it started perfectly. Waited 2 min shutdown, waited 2 min started up, perfect boot. But now the mini is saying it only has an internal sound. I have to unplug the headphone cable and replug it, then it works great. What the heck could cause this? It never ever did it in my house so the only thing I can think is the carnetix is doing something incorrectly. I have not heard back from Mike yet either. I doubt it is the mini bc it never happens in the house. Any ideas? I know I can buy a usb soundcard but I would rather just use the mini's built in sound.
That is exactly the issue I have, I never tried it in the house though. As mentioned earlier, using the headphone on the sound card doesn't have this issue.Originally Posted by skippy911
As far as what causes it, no idea really. It also does it for me if I turn the Mini off and back on (or manually sleep & wake it) while the car is still running (i.e. leaving the LCD and AMPs powered through the whole sequence). Given that I am not sure how it could be the p1900, but I suppose it could have something to do with it doesn't happen on AC.
How did you test it in the house (i.e. what was plugged in)? If you haven't, try doing a mini -> RCA connection to a Stereo AMP/Receiver since that should be closer to the in car setup and see how that does.
Might also be worthwhile to run an extention cord out to the car and run the Mini off it and see if it has the same problem with the car stereo hooked up.
Is there a osx command to switch the audio port off and back on? Im wondering if a script can be written to auto run when the mini comes back from sleep. Only thing I can think is maybe the p1900 doesnt supply the right voltage or something that the audio port needs when it wakes up to know the sound is plugged in. Like i said it works great in the house so I dunno how it could be anything but the p1900 in the car doing it. I searched the mac mini forums on apple's site but couldnt find anything about it.
Ok I think I solved the last piece of the puzzle. A targus port replicator. The ethernet, serial and parallel ports dont work in osx, I emailed targus about a driver for osx, but the good thing is it is a usb 2.0 hub and has built in usb audio. I will do some more testing tonight when I get home but this looks like a viable solution for the audio issue and will also eliminate me needing a usb hub since it is built in. The model number is PAEPR090 here is a link http://www.targus.com/us/product_det...?sku=PAEPR090U ill let you guys know how my testing goes Maybe ill keep the mac after all hehe. Oh, and when I went out to my car a few hours after my last test, the mini woke from sleep with no problems except the audio not working.
Cool. Glad to hear you are making progress.Originally Posted by skippy911
You might still need/want a USB hub though. If it draws it's power from the Mini's USB, it (or more specifically devices connected to it) could cause the Mini to wake from sleep when you don't want it to. Check out the Carnetix forums for info about that.
For the record, I have the Belkin 7-port hub and it only draws power from it's DC power source so it is car friendly Though the power connector is loose so it drops power from time to time (better now that i've stablized it, but still happens from time to time).
