Hi:
I'm using the next-to-the-latest firmware (waiting until neurosdbm can do the new artist->album thing before I go 2.14) and I am STILL encountering skips during playback.
They aren't as bad as they used to be, but they're maybe about a 1/2 second or so. Today in particular I seem to be having a lot..maybe I'm just noticing them more.
I notice in the readme for the 2.14 beta there is no mention of the skips, and it claims there are no outstanding issues. Am I the only one hearing these skips? They're quite annoying...it's like someone had bumped your CD player during playback (well, not that dramatic, but you get the idea).
Note, this is NOT the old broken-record skipping problem from several firmware revs ago...the skipping was happening DURING playback, seemingly at random even back then. It's not as bad as it was, but it still happens. Are there plans to finally fix this?

| Are they happening during MP3 or Ogg playback? What bitrate or quality are your files encoded at? |

I should have mentioned this in my last post: it's all in Ogg playback (but I don't have any MP3s so I don't know if it's happening there). All my Ogg files are encoded -q5. It's not MyFi, this is all over the headphone jack.
The skips happen at random. If I replay the same song it won't skip in the same place (something that used to happen several revs ago when the skipping was common). |

This is called "chriping", which is technically different than a chrip.
Sort of a high-pitched blip?
These are usually on high-encoded Oggs through MyFi. Is that the case with you?

Nope, there is no blip. It's not a chirp--I remember the chirps from the 1.x firmware days.
It's a skip. The song skips ahead probably 1/2 a second or so, literally like someone "bumped" a CD player. It happens anywhere in the song, beginning, middle or end. I haven't heard a blip since the 1.x firmware. :)
Like I said it used to be more dramatic in the earlier 2.x series. The skips were over a second, and they happened usually in the same places in the song. Now they're shorter, but completely random.

| How did you encode your Vorbis streams? What version encoder? Have you tried re-ripping any tracks? Are there any tracks specifically problematic? |

I encode them the same way I've always encoded them--with xiph.org's oggenc, version 1.0. None of my music is encoded with a pre-1.0 encoder.
oggenc -o %m -q 5 -a %a -l %d -t %n -N %t %w
(taken from my .grip file).

Oh and to answer your other questions no, no particular track is problematic--it's random. If I replay a track that had a skip, the skip is no longer there. I don't see any point in re-encoding them since they're all done with a perfectly valid version of oggenc.
(And I'm not going to re-encode 3,000 tracks either...it took me WEEKS to encode my whole CD library before, I'm not planning on revisiting that.)

| I have the same problem. I also use vorbis q5, and firmware 2.13. I cannot figure out if there's any pattern to when it happens. I'm not sure exactly what's happening, but it sounds as if the playback is suddenly in a different position - not too far off, but enough to throw the beat off. Happens on average perhaps once in an album, but sometimes seems to happen more often. |

I have this problem also, but I have not yet reported it for two reasons. Firstly, I've been too lazy to scour the forums to find this issue (it has been mentioned from time to time, but searching for skips tends to yield more about the broken record problem exhibited in earlier firmware). Secondly, I have not yet been able to figure out a way of reproducing the problem. It appears to be purely random. I thought perhaps it was when the hdd spun up or the like, but if I recall correctly, the hdd was not spun up when I checked just after any of these skips. The vast majority of my oggs are encoded at quality 4 and I am using the 1.0 Vorbis codec (i.e. 20020717) with CDex 1.51.

So can I assume the skipping problem is not considered a high priority? I find it hard to believe that only a small few of us are encountering it.
For what it's worth I'm still having these annoying skips even with the latest firmware (2.16). As far as I'm concerned this is the only thing that keeps me from saying my Neuros is "perfect" (but hey, 99% isn't bad either is it?)

same problem here, 100% ogg collection. exactly as kgf describes it. doesn't bother me overmuch, but would be nice if it was fixed.

| Happens to me too. I encoded all my CDs recently with cdex 1.51 using 1.0.1 at q5. Of course, I also find these skips annoying. They seem to happen more frequently with q6 encoded oggs, so I figure it is just the 2.x way of handling oggs. Instead of the high pitched chirp/skip of the 1.x firmware, now you get a silent skip. I can tolerate the silent skip much better than the chirp/skip. I almost went back to MP3s because of that chirping. |

Interesting. I've finally got a reproducable "skip". I just got my new Starseeds CD yesterday and encoded it -q5 (as I usually do). The first track, "Starman", skips every time in the same place, within the first 10-15 seconds of play.
It is not a problem with the Ogg file since it plays fine on my PC. |

Consider sending that track in to DI for analysis.

Of course your PC is only what, 100 times more powerful than the Neuros?

No, I wasn't referring to the power of the player, I was referring to the file itself; it's not "flawed" in any way.
Who would I send the file to? Is there an email address or contact for that? |

I think Chameleon's point is that maybe there is something about this file such that the Neuros is having trouble decoding it. Maybe it can't decode it in real time, for example, but your PC can because it is many times more powerful.

Try another media player. I can hear defects on some players, and not on others.
You might want to try re-ripping the song.
If it's a skip in the same place, then it is on the file. The garden variety chirping problem we all talk about is random, sometimes is happens in some places on some songs, and then when you replay, it won't do it again.
As an aside, I was talking to an engineer from our parent company (of sorts) that makes the Skip Dr. One interesting thing he told me is that all CDs have errors in the files. But as soon as you rip or burn a CD, its RIDDLED with errors, most of which you can't hear. Like you may notice it takes a lot to scratch a CD you get from the store, and CDs I burn myself get scratched very badly, very easily.

The random skip surely isn't just caused by CD defects is it? Are any MP3 users hearing these skips?
Is this an "open issue" at all with Neuros? Just curious. |

Doubtful. Just a lack of power in the device. Those skips are buffer underruns. I wonder if there was a way to increase the buffer size of Ogg playback...
