OpenELEC Testbuilds for RaspberryPi Part 3 (Kodi 14.0)
Hey, are this helix builds suitable for 256Mb pies?

Should be. I'd recommend you ensure gpu_mem=112 and cachemembuffersize is unset (so it uses a lower default on 256M Pi).
On a 256MB Pi, you might want to consider adding swap by running configrpi256.sh.

i tested around with the new builds. The sound is fine without GPU acceleration except for 24Bit/192kHz files. The sound is not like white noise. I think the playback is to fast.

In the log file i see the following error:

Code:
20:23:51 44307.937500 T:3033527376   ERROR: CAESinkALSA - snd_pcm_writei(-32) Broken pipe - trying to recover
20:23:53 44309.691406 T:2699031632   ERROR: Previous line repeats 34 times.

Here is a debug log

Playback via HDMI to my TV is fine. Here is a log

But at the moment i am very happy to use my HifiBerry again Big Grin

Thanks to all persons which helped me!!!

EDIT
If i set the output to 96khz the playback to slow. When i set the output to 44.1khz the playback is even slower

Hi,

with build #1007 the problem is gone Big Grin. Now the HiFiBerry DAC is full usable Nod

MANY thanks !!!

EDIT: resample via GPU is not working but this is no problem for me
Hi BoBeRzE,

what are your loaded modules in '/storage/.config/modules-load.d/hifiberry.conf'.
I hear only 'white noise' with build #1007.
Or still you have other special settings?
Hi a4741488,

here is my hifiberry.conf

Code:
#snd_soc_bcm2708
snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_pcm5102a
snd_soc_hifiberry_dac

It could be that u use GPU accelerated resampling

System -> Settings -> Audio output -> Resample Quality and chose High or another value exept gpu accelerated.

popcornmix meant that the accelerated resample path is buggy at the moment

Thanks a lot....'changing the resample quality'...thats was it.

    • Add bcm2708_gpio driver
    • ARM: bcm2708: Limit the boot time interrupt allocation
    • ARM:bcm2708: Add Support for Wolfson Audio Card
    • ASOC: RPI : Add support for Wolfson Audio Card
    • config:RPI: Add config support for wolfson audio card
    • ASoC:RPI: DMA channels 2 and 3 to be set in FAST mode

It's entirely possible the switch to 3.17.y may have broken existing functionality, particularly USB/GPIO audio, so please test and let me know.

It would also be great to hear from anyone using a Wolfson audio card, ie. whether it's working or not.

At a guess, the Wolfson may need the following /storage/.config/modules-load.d/wolfson.conf:
Code:
snd-soc-wm5102
snd-soc-wm8804

The Wolfson config may also require one or more of the following:
Code:
snd-soc-arizona
gpio-arizona
extcon-arizona
arizona-i2c
arizona-spi
snd-soc-wm-adsp

Is force_turbo=0 ignored in this build? Dynamic overclock seems not working fine.

Yes, looks like it's not scaling the frequency - I probably set one of the kernel options incorrectly, though not sure which one. Popcornmix?

This is the dmesg for a system booted without force_turbo, arm=1000 and it runs continuously at 1000Mhz, even while idle.

Edit: Hmm... well, I stopped xbmc.bin and then the ARM and Core speeds briefly dropped from 1000/500 to 700/250, so it looks like frequency scaling is active, but maybe too sensitive? bcmstat output.

I had a quick look at it, but didn't get very far.

A fresh installation without any additional config shows these modules loaded - question: where do they come from, some device tree config?
Code:

lirc_dev                7885  1 lirc_rpi
rc_core                16223  1 lirc_dev
bcm2708_rng              812  0

One thing to note is that it's a good idea to either blacklist lirc_rpi or set it's gpios to 14/15 - otherwise it'll conflict with the wolfson card.

After some tests with minor success I tried disabling a few modules which I though maybe could conflict with the wolfson drivers (not sure, though, will have to check later):
Code:
blacklist lirc_rpi
blacklist lirc_dev
blacklist snd_soc_pcm512x
blacklist snd_soc_pcm512x_i2c
blacklist snd_soc_tas5713
blacklist snd_soc_wm8804

And enabled these modules:
Code:
arizona_i2c
gpio-arizona
extcon-arizona

snd-soc-wm5102
snd-soc-pcm5102a

snd-soc-wm-adsp
snd-soc-rpi-wsp

This lead to the following lsmod:

And this dmesg: http://sprunge.us/QGHi

"Failed to allocate IRQs" certainly doesn't look OK - but at least the voltage warnings are only temporarily at the beginning. Edit: but the "fixed" (fixed voltage regulator) module usage count seems to be strange.

Edit #2: here's /proc/interrupts:
Code:

Another try, without blacklisting snd_soc_wm8804 gives this modules:

and this dmesg: http://sprunge.us/QdWI

Now I'm stuck. Any ideas what I might be missing?

so long,

Hias
Thanks for the feedback, HiassofT. I'll be keeping an eye on PR:705 where you've asked the Wolfson developer for details, and make any changes as necessary though hopefully it's now just a matter of getting the right modules loaded.

As I'm unable to reproduce your testing environment let alone your problem, I can't really contribute more than this.

Reproducing your issue is crucial to understanding and finding a solution, but obviously reproducing is not easy otherwise I'm pretty sure it would have been solved already.

Hi popcornmix,

As you can read above, Milhouse is not able to test and fixe the drops I have when playing HD audio files.
So, now you are my only hope.
Could you tell me if you can fixe and test, with my help of course, the issue in a reasonable delay? (2-3 months I'd say?)
If you can't I'll have to consider to buy another hardware player and maybe software as I can't listen these audio files.
Thank you in advance for your answer.

I added the audio latency gui settings hoping it would help you.
I tested a couple of the 2L files on 50ms, 100ms and 300ms and with channels set to 2.0, 2.1 and 5.1 and they all played fine for me, so I'm not sure what to suggest.
