iriver h140 ... Det väckte lite minnen, en sådan köpte jag våren 2004 (eller rättare sagt en iHP-140, som den då hette). Efter flera veckors väntan på en mjukvara som eventuellt skulle fixa några fel, så reklamerade jag den. Fick se att dom fortfarande släpper mjukvaru uppdatering till den! Tänk om dom hade släppt några när jag väntade. Undra om dom fixat felen.
Klistrar in lite text som berättar om felen...
I have discovered some problems with the iHP-140, which I just have bought. These problems concern recording and playback of WAV (44.1) files via the digital optical connectors.
1) Recording:
At recording samples are lost. I have recorded a track from my normal Sony CD player. The track is 2 minutes and 36 seconds long. During a recording of this track 3 times samples are lost. I have repeated this several time with the same result, but numbers of samples lost and there it occur differ. Here follows a list of 3 recordings and number of samples lost and at which time it occur:
Rec1: 0:45 44
0:59 1
2:06 43
Rec2: 0:25 51
0:59 1
1:45 44
Rec3: 0:58 1
1:04 50
2:24 45
The harddisc is starting up every half minute and is on for 10 seconds. Some faults occur while action is done with the harddisc, but not all. So the fault is not directly associated with the buffer full (harddisc on) time. It's either 1 or 43-50 samples that are lost. Note that for Rec 1 and 2 above lost one sample at 0:59, but the two recording did not lose exactly the same sample (the time is truncated to seconds).
To verify that it is not the Sony CD player that does the fault I have done two things:
A) Use a PC to record the data from the Sony CD player. This without any fault (all sample/bits are the same).
B) Make a recording with the iHP from the PC. This with faults similar as when the Sony CD player there used as the source.
My conclusion is that the iHP has some serious fault in the recording part.
2) Playback:
At playback the first 1152 samples of a track is zero and the last 384 samples is zero. In other words, some part is lost in the playback. The rest of the samples (the big part) are the same as the source, i.e. no bit faults. Of course all of the track should be played.
