I assembled my MintyPi 2 days ago, and it was fine to begin with. Now, sound has stopped working. My soldering is also fine (take my word for it, I've done a lot of soldering in the past. I also don't have my camera on me ). I've done continuity testing and found that my data positive on the pi seems to be shorted to ground. This is inexplicable because it worked fine a day ago and the port is entirely clean. I don't know if that's normal or not, but that's my main suspect at the moment. Any thoughts?
I get this error:
AudioManager Error - Unable to open SDL audio: ALSA: couldn't open audio devices: Device or resource busy

Re: Minty Pi USB issues
Update - I've tried:
-Swapping the pi
-Swapping the sound cards (twice)
I'm still getting the same error. I know the device is recognized somehow because if I wire it improperly, the splashscreens don't show up on boot.
Edit:
I'm not going to bump the thread any more so here's another update:
It now makes a really loud buzz. It's not noise. I have no idea what the problem with this damned thing is.

Re: Minty Pi Audio issues
How are you wiring the audio output from the soundcard? I've had a bad trace from the audio pads under the pcb near the battery monitor chip to the top traces where the speaker pads are.
I would test a speaker to the sound card directly to rule a bad trace.

Re: Minty Pi Audio issues
I'm not home, so I can't check right now, but I don't think there's a bad trace. When I turn on the console, after a minute or so of silence, it will output a really loud monotone buzz. There was a point at which it started working, but when I rebooted it it began buzzing again. I'm considering reformatting the SD card when I get home because it seems more software than hardware.
Re: Minty Pi Audio issues
I am having the same issue, but the sound works at first, then gets scratchy, then cuts off. Then after 10-15 seconds or so (could be a bit longer), the sound comes back on and is fine. It then does it all over again. When it is off, I can go to the audio portion of the menu, and I get the same error that Sushi gets. It could very well be my soldering job. Just wondering if there was ever a solution to this. I was thinking of reformatting the SD card too.

Re: Minty Pi Audio issues
Sounds like a power issue and or solder job, have pictures of the solder job?
