HI
I wonder if anyone can solve this one:
I have several USB sound adaptors, which cost just a few dollars on eBay, and plug into your USB port to provide additional sound out paths on a Mac.
These devices are tiny USB plugs that actually contain a digital-to-analogue sound card converter, and have a microphone jack (3.5 mm) for audio input, and a headphone jack for audio output. Even the USB sound adaptors that are designed for PC work fine on the Mac, and without any driver. And as I say, you can pick them up for just a few dollars.
I find these USB sound adaptors useful. I have three of them, and I can connect various pieces of audio equipment to each of these USB sound adaptors (such as my headphones, my hi-fi, my multimedia speakers, etc), and then conveniently switch the Mac's Sound Out to the required USB sound adaptor, just using the Sound Control panel.
This means that I don't have to start plugging my headphones, hi-fi, and multimedia speakers in and out when I want to use them: I just change the desired output via the Mac sSound Control panel (or even more conveniently, via the freeware "SoundSource" menubar sounds source changer).
This all works very well.
However, quite often when my MiniMac wakes up from sleep, one or more of my plugged in USB sound adaptors will become effectively unmounted, and no longer responds. Of course, pulling the USB device out and plugging it back in again fixes the problem, but I would like to know why they do not wake up from sleep, and become inactive or unmounted. I also have a USB hard drive plugged in, and this has no problems with waking up after sleep.
One solution is perhaps finding some software, or an Applescript, that remounts all USB devices after my machine wakes up from sleep. Does anyone know of such a utility?
But I will be grateful for any other suggestion as to why this is happening, and on how to fix the problem.
Many thanks for your assistance with this.
