Apologies if its been addressed, but I believe i have a very strange sound issue that I haven't been able to resolve. I have a 1st Gen iPod Touch 16Gb, that when I got it was in Firmware 2.2.1. When I tried to play music, video, or youtube, there was absolutely no volume. I downgraded to 2.1 and voila I got sound. However I wasn't able to adjust the volume at all, even though the volume slider was available. Tinkering around in the settings / music did nothing. I downgraded again to 1.1.5, and again no volume. I upgraded to 2.1 and again I can hear the volume, but no ability to adjust the sound. I've installed/uninstalled multiple iTunes through this process, and even jailbroken this iPod, but still no ability to adjust the sound. It doesn't seem like a hardware issue, since I can hear the sound, just no ability to adjust. Can someone help???
