(clip+ already has CDDV2=113, so no 3rd link)
I guess people should try them in the order given, so developpers can know how much the other patches are needed.
(I haven't tested them, so use at your own risk.)
I am trying these on two different clip+:
- on an older refurb both builds crash very fast (browsing the file system, FF through an mp3). With an SDcard even worse.
- for a newer one the first build seems stable so far, also with the SDcard inserted. Needs further testing.
Both are AMSv2 variant 1.
BTW, it seems the patch that prevents the click when traversing the -40 volume value is not included (posted by Mihail in this thread).

Can you test this build: http://knk.zz.mu/rb/clip+.zip ?

All audio patches already commited to rockbox. We switch audio mode when traversing the -40 volume value, so small click unavoidable.

Hi Mihail,
your build works fine, I couldn't break it so far ;-)
As for the "audio patch" I know that Saratoga had commited it. I DON'T hear the click in the current dev builds nor yours, but in the one by LolaPalocz.

Can you also test next two builds?

Very strange. You should have small clicks/distortion on all builds. Better do cold restart (power off and than power on) after installing new build.
I hear more noise and have more power consumption when restarting without power off.
Scalpos:
OK, did some tests with my 3 years old Clip Zip, AMSv2 variant 1; it is loaded with a 32GB Kingston µSDHC Class 10 / UHS-1 reported as SD32G Rev 3.0, Prod: 1/2014, Ser#: 0x00124ACE by Debug/View disk info. Database and dir cache are disabled.
- amsv2_scaling_v8 seems OK, but I experienced µSD card instability: songs played from the card were sometimes skipping to next one after 10-30 seconds, and after reboot Clip often displayed "nothing to resume", just as if the card was missing, and indeed it was not available in files browser. Playing from internal memory was fine. I live in France, and temperature has not exceeded 27 °C the last few days, so it's up to you to decide if this SD card instability might be related to the climate ;)
- amsv2_scaling_v8+gui_boost+restore_irq has what looks like the same µSD card instability as previous build, plus when the clip was linked to the PC, drives show up, but Windows was not able to recognize them properly. I tried many times, rebooted both the Clip and the PC, with or without the card. Finally, as I had no access anymore to the Clip internal memory from PC in order to update it, I copied with the 3rd build's .rockbox directory onto the card and once loaded into the Clip, I copied it to internal memory. The copy partially failed, but it was enough to have access again to mounted drives with the Clip linked to the PC (full Rockbox reinstall avoided, fortunately).
- amsv2_scaling_v8+gui_boost+restore_irq+CVDD2_113 looks fine so far, no more SD instability for the moment. Had only one issue: at power on, load was stuck displaying Rockbox logo step; ejecting the card, power on + loading the card after the Clip had properly started was enough. I only played few hours with it and will use it as usual this week. I already noticed estimated autonomy looks funny, don't know if Rockbox is lost with the battery improvements. The remaining power percentage shown sometimes jitters: 75% is displayed, then 74%, 75% again and few seconds-minutes later it's back to 74%. Shall I reset anything in order to have it properly calculated, and have it taken into account by Rockbox Information panel ?
Let me know if providing any logs (and how) would help.
BTW, I did not notice any GUI lag using all three builds, Clip was of course restarted after every update.
