If it was #1208, then PR8497 and the pulse audio changes look like the only music related changes.

Can PR8497 be excluded in a subsequent build? Or perhaps a fork?

I've unzipped the two albums and have played them from Music > Files (over smb://)

Both albums play without any problems, with no lockups.

However the Hillbilly Holiday tracks all give the following output so this seems to be some sort of encoding issue:

Will see about reverting PR8497 in a test build.

Interesting.

Using >> Files the problem does not occur. At least to my layman's eyes, that makes PR8497 even more likely to be the problem.

@bill_orange: Here are two RPi2 test builds. Try them and report which works best, assuming there is any difference at all.

#1212y: Reverted PR8497
#1212z: Reverted PulseAudio -> ALSA Bridge (PR:4509 and PR:4482)

Hello,
with #1222 i notice stuttering video and artefacts at beginnig to start the "Tina" DVD.
Buffering is also little higher than build in build 1221.

Sample _Test.7z is on GoogleDrive, you know.

I don't find the option to enable 8 chanel pcm decoding for hd audio. Is this automatically done if bitstreaming is disabled?

Automatically enabled on Pi2, disabled on Pi1.
Bitstreaming takes precedence though, so disable DTS passthrough if you want 8 channel audio.

Any news on this front?

I did add some settings you could try tweaking so see if they help. Use this firmware:
https://dl.dropboxusercontent.com/u/3669...re_arb.zip

(Use start_x.elf and fixup_x.dat and replace your OpenELEC start.elf/fixup.dat).

This has a new command you can run from ssh. It allows setting the priority of different blocks on the Pi.
Code:
$ vcgencmd arbiter
usage: arbiter [ status | algorithm <arbiter> <credit|priority|hybrid|delayed> | set <block> <priority> ]
$ vcgencmd arbiter status
SYSTEM_UNCACHED: alg:hybrid
      SYSTEM_L2: alg:hybrid
     SYSTEM_SRC: alg:hybrid
    SYSTEM_PERI: alg:credit
     SYSTEM_DMA: alg:credit
   VPU_UNCACHED: alg:hybrid
         VPU_L2: alg:hybrid
            CAM: alg:credit
    HVS: pri:12 panic:15
    V3D: pri: 0 panic: 0
   H264: pri: 8 panic: 0
   JPEG: pri: 0 panic: 0
   TRAN: pri: 2 panic: 3
    ISP: pri: 4 panic: 0
    USB: pri:13 panic: 0
ARM_UC: pri:10 panic: 0
ARM_L2: pri: 5 panic: 0
ARM_PER: pri: 8 panic: 0

I think the first test is to make HVS low priority and see if that helps.
Code:
vcgencmd arbiter set hvs 0 0

You might also want to set the ARM to be high priority
Code:
vcgencmd arbiter set arm_uc 15 15
vcgencmd arbiter set arm_l2 15 15
vcgencmd arbiter set arm_per 15 15

Or low priority
Code:
vcgencmd arbiter set arm_uc 0 0
vcgencmd arbiter set arm_l2 0 0
vcgencmd arbiter set arm_per 0 0

USB can't be changed when running, so you can't change that.
V3D should have an effect, but we have experimented with that before.

this setting works best for me
http://sprunge.us/fJVa

but still some rare artifacts

hvs 0 0 and or arm 0 0 are even worse

green artifacts are still there when watching 720p channels
could this be a usb problem and no deinterlace problem?
today I tried setting usb to 1.1 with dwc_otg.speed=1 but my tv card doesn't support usb 1.1 so I can't test if it would improve anything.

Can you provide a debug log showing the corruption.
There is one reason where corruption can occur when the video stream is considered stalled and reset - I'd like to know if that is the cause.

No but I've just updated it. Currently untested (except a compile test) so please report if it work okay in tonight's build.

hi popcornmix

Well, have uploaded

Tzz, the problem is not so strong @#1223, if Debug Log is aktivated.
But KodiCPU is over 100% if video begins.

Merry Christmas!

@doldi can you try again with sync method set to "resample audio" rather than PLL adjust.
