Every time it happens and I look at the progress bar, it occurs at exactly 3 seconds from the end of the song. It bounces around back and forth between 3 seconds and close to zero before it moves on to the next song. </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1871 Thu, 12 Jan 2012 14:04:47 +0000 Joey Butera 1871@http://www.dpsinsider.com/forums/ <p>It turns out this is probably related to the ring buffer. This is an area our developer is always tweaking to really iron out the kinks. As I understand it, this part of the code must allow for the different bit/sample rates of each audio file as well as the performance of the device. I know this buffer also throws console notices in the Mac iTunes plugin but they don't cause any issues. Perhaps one of the savvy programmers on this forum can elaborate as my knowledge ends here!</p> <p>Anyhoo, they are aware of the issue and will continue to improve this area of the code. </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1869 Thu, 12 Jan 2012 12:46:55 +0000 jimboden 1869@http://www.dpsinsider.com/forums/ <p>Just for the record, this problem also happens with music purchased on iTunes, which is 256kbps, so it doesn't appear to be related to importing CD's. </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1865 Tue, 10 Jan 2012 15:14:38 +0000 Joey Butera 1865@http://www.dpsinsider.com/forums/ <p>Yea, it's odd. It only happens to me when I listen to Radiohead. Go figure! </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1863 Tue, 10 Jan 2012 15:06:28 +0000 jimboden 1863@http://www.dpsinsider.com/forums/ <p>Just an update. The next day I listened to music for well over an hour and this problem did not happen once. I also listened to some of the same songs which gave me a problem the day before. Very strange. I know it doesn't have anything to do with how well charged the battery is, which is something I suspected. Both times the battery was well charged. </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1862 Tue, 10 Jan 2012 15:05:14 +0000 Joey Butera 1862@http://www.dpsinsider.com/forums/ <p>Thanks for the detail on that, Jim. I'm passing this info to the project manager now. </p> http://www.dpsinsider.com/forums/topic/dps-122-for-ios-audio-problem#post-1860 Sun, 08 Jan 2012 13:03:19 +0000 jimboden 1860@http://www.dpsinsider.com/forums/ <p>I actually reported this problem a while back with an older version of DPS. I upgraded to 1.2.2, which works great. The upgrade fixed a problem I had before, where DPS would not play videos stored in my photos library, which now works well.</p> <p>The audio problem I reported previously still happens with DPS 1.2.2. Specifically, the audio breaks up into what I can best describe as static or random noise. It happens right near the end of a track. I was listening to the song Chasing Cars by Snow Patrol. When the song was almost over, it suddenly broke up. I took a quick look at the screen and noticed that the progress bar was jumping around in the last few seconds of the song. It was going back and forth while generating the noise. It didn't complete the track, so I had to force it to the next song. This album is reported in iTunes as 256kbps (VBR), which I imported from a CD using AAC encoding and iTunes Plus. I replayed the track to see if the problem recurred, but it played fine the second time. I was listening to a playlist at the time, and this problem happened at least 3 times while listening to no more than 15 songs.</p> <p>I have a 64GB iPhone 4S running iOS 5.0.1. I'm using iTunes 10.5.2.11 on a Windows 7 64 bit system. </p>
