iOS 5.1 AAC encoded music with "High Efficiency" is not playing

First of all, I don't think "millions of users" have encoded their music in that format...since it is a low bitrate format, good for streaming and such, but using that as default format for your iTunes library is like driving your car on the sidewalk...it works but it is not good. ;-) But anyway, re-syncronizing your iPhone should relieve it in most cases.

Hi,

i see this topic lately, having discovered the problem this week end, but it's mine too. I did rip my Cds using m4a aac+ (CBR 256) codec (the high efficiency of EzCd) and they are not playing anymore. Is there any new from Apple about this downgrade or bug ? I use Iphone, Ipod, and at home a Dvico Tvix and the best compatible format between the different players was this codec (no m4a lossless on Dvico, no flac on Iphone).

I'm not sure that we may be millions to be in this case, but as it's the ripping of my more or less 700 Cds, with the ability to hear them on different brands, it's a kind of job i would not like to have to do once more for an Ios bug 🙂

Thanks by advance for any new 🙂

Hello,

i do understand your problem, which is mine too ... just that i did update to IOS5.1 last week end, and did not try to hear at any music on it until yestearday... m4a lossless works fine, only the recordings in aac+so it's clearly a downgrade or a bug, and i'm not wanting to re-rip neither 🙂

AAC+ (HE AAC) 256 is clearly a good format, not lossless, but great for many classical recordings that are not digital or recent. If not listed as a downgrade, it's a bug or something 'forgotten' in the last IOS.

Other explanation could be the end or the lack of use of this codec ... i did read few lines about it being taken to dolby aac on the poiko site.

In any way, and as you are, i'll be glad to read what Apple have to say about it, as it is, whatever the reason, a functional downgrade.

Regards

I have been encoding my CDs for about 6 months with Dolby Pulse AAC format at 320 kBPS and it has stopped working since iOS latest "downgrade", too. Very frustrating!

Frustratingly I see there are no posted solutions as of yet and am wondering if anyone has in fact resolved this annoying issue. If so, please be so kind as to post the solution online.

To reiterate, the problem presented itself AFTER I upgarded to IOS5 in that all my original songs that used to work before the upgrade (encoded with High Efficiency) will in fact still play in Itunes but NOT on my Ipod Touch.

I've the same problem and I want to know if upgrading to 5.1.1 solves it.

Hello,

i saw no better result, but i did find a solution : i did buy an App reading flac encoded music. Part of my library was flac, part m4a aac+ ... i did rework from my Cds the m4a in flac, (400 in around one month) and that's done ... bad new : it takes more place on the phone ... good new : the sound is always perfect, as it's lossless and free of any brand (not an other m4a) ... good new (2) : i do encode only once (for my Tvix Dvico and my Iphone), so it's faster.

I think that Apple does not want to pay (anymore) for the Poiko codec, and that's why it does not work anymore since IOS5 ... there was in the (far) past a similar situation with a mp3+ (enhanced) created by Thompson ... very good but noone wanting to pay for it, so not used anymore 🙂

The iTunes App Flac Player was around 8 euros and works well (not perfect, but good) and the small equalizer is fine. So that's a quick and not so expensive solution (compared to the amount of music not readable).

I don't thank Apple for this functionnal downgrade, it's anything but fair, but i'm back now in a free situation (no link to a Apple dedicated codec), and then may be more free to choose between I5 and S3 at the end of this year.

I hope that this can help someone in a similar situation.
