Poor sound quality on X5 with RockBox
AlexP:
I can't hear them or iriver h140 - I luckily also have a H140 that doesn't tick with the remote, so I don't know if that might be related.

Thank you very much, Llorean and others, who supported me. Thanks to Mike Sevakis (26/08/2006), the problem with inaccurate stop is solved! The stops and starts are accurate and almost as in OF. Light clicks are heard on volume change, but nearly the same as in OF, though RB still has a huge click on shutdown.
What is really annoying me, it is still (4) number from my first message. Light clicks, which are hear while listening to FLACs at normal volume. I cannot figure out how are they created and where from do they go... But they are:
1) Heard at -36 volume (!!!!!!!!!!!!!!!!!!!) in quiet place (Koss Porta Pro)
2) Go in 3-packets: (click-click-click)=1-1.5 sec.
3) Sometimes they are not present.
4) Reproducible from time to time
5) They are some kind of CD clicks, but neither original FLAC or FLAC in OF reproduce these clicks.
I think they are not present in OGG files. Any ideas, please? I beg these clicks ARE present and they are NOT of a hardware cause. On FLACs. 44100, 16 bit, ripped from CD.

I've noticed sporadic clicks/skips with long low-bitrate Ogg files on X5. They occur every 10-30 seconds and are like a 1-2 second audio dropout. The files are around 32kbps mono (22050 Hz), from 3-4 hours long. They don't occur on a PC.
I haven't been able to consistently reproduce the problem, otherwise I would've filed a flyspray report.
Llorean:
The Rockbox resampler is less than ideal, so anything not at 44.1kHz may have fairly noticeable artifacts.

The big click at shutdown was solved a long time ago my RaeNye by powering down the TLV320 nicely. x5 just has a whoosh like OF. I enabled zero-crossing detection for the volume control which softens it up as much as it will ever get without software intervention.
