What I'm hearing, is that when I some music files, it sounds like it is really low quality. Like an mp3 compressed to 48k (or less). The singing in a song is hard to hear, it all just sounds muddled. Listening to music in the browser and Pandora both had this effect. I haven't loaded any mp3's yet (been busy learning and rooting, etc) but I have downloaded a few ringtones, and they don't seem to experience this issue.
Listening to Pandora has been both through the built in speaker, and the headphone jack to a speaker system. Horrible on both. Also, I was using Google's Listen to listen to the most recent episode of the Engadget Podcast, and with the volume all the way up on both the Captivate and the sound system, I still couldn't really hear it. I unplugged and listened to it over the phone's speaker, and it was audible enough to hear, although not at all loud, even at max volume.
Thanks a million for the links to those threads! I searched and searched and couldn't find anything relevant to my issue. Did you have prior knowledge of those threads, or did you find them by searching? If so, I'd like to know what keywords you used (if you don't mind). I'm always trying to improve my ability to help myself, so I'd appreciate it. It's late now, so I'm going to fully read those threads and try the fixes in each tomorrow. I'll report back. Also, I'll test my wife's Captivate to see if it has the same problem. **** it, I'll do it now.
Results: Pandora sounds fine through the internal speaker, when plugged into the speaker system (iPod dock w/aux in) it immediately sounds like ****. Perhaps the bad quality is only when plugged in, I might have just thought the internal speaker sounded bad because it's tiny. I'll retest my phone in the morning.
