I noticed an odd hissing sound coming from my 4S's speakers, both with headphones and without. It only occurs at high or max volume. I can get it to make the sound if I pause the video/song, put the volume on the highest setting, and quickly un-pausing and re-pausing the video/song. The hiss goes away when I lower the volume or the phone makes any other noise. Does anyone else notice this?
What's even more odd about it; I synced my older ipod touch 2G with iTunes and now it does the same exact thing (I don't know if it did before). I tried restoring both of them to factory settings and the noise still persists under the previously mentioned circumstances.
Maybe this is a "feature"? It can't be the hardware because it happens on both devices, and I don't think it's a firmware issue because it still occurs after a factory restore.
Please try what I mentioned earlier "I can get it to make the sound if I pause the video/song, put the volume on the highest setting, and quickly un-pausing and re-pausing the video/song." and tell me if you hear a hiss as well. If not, what should I do to get this repaired. Thanks!
