No sound - Raspberry Pi Model B + Audiophonics DAC PCM5102 I

makfredo

Hi,

I'm very annoyed by this: I get no sound at all while playing, either from USB or from my NAS. There's nothing wrong with my hardware setup, as I don't have that particular problem with Volumio. I'm using an Audiophonics DAC PCM5102 I2S P5 32bit/384kHz on a Raspberry PI Model B.
What might be the problem here?

Here's the debug data on Pastebin : http://pastebin.com/4tZE6yJg

Still not working… I thought it could be a SD-card-related issue, so I switched for a new one but no cigar!
Just in case, here's a pastebin link to a dmesg dump: http://pastebin.com/QW7cPdkC
This is so frustrating!

Hi makfredo,

there is nothing special in your dmesg dump.
You have selected the DAC under menu->MPD ?

Please provide us your debug data.

HOW TO COLLECT AND POST DEBUG INFO

In the RuneUI, go to MENU > Debug;
Click the "COPY DATA TO CLIPBOARD" button;
Go to http://pastebin.com and paste the debug output in the "New Paste" textarea. Leave the default options (Syntax Highlighting: None, Paste Expiration: Never, Paste Exposure: Public), give a name to il (e.g. RuneAudio debug info) and submit.
Copy the url of the submitted Pastebin (e.g. http://pastebin.com/dL1k9irT) and include it in your post here in the forum.

Hi Frank,

As a matter of fact, the pastebin link to my debug data is in my first post. Here it is again: http://pastebin.com/4tZE6yJg
I did everything as required, trust me… Yesterday, I flashed a new Class 10 SDHC 16 GB card, updated RuneUI, did all the settings all over again… Still no sound.
And I had an intuition: what if the trouble originated from the kernel? In the menu, I then selected the 0.3-alpha kernel and rebooted… And to my astonishment I had sound at last!
That's why I had sound in Volumio and none in Rune… But it still seems odd to me!

Hi makfredo,

sorry i didn't see the debug data from your first post.

This is strange, because my Hifiberry DAC works with this image and the Linux kernel 3.12.26-1.
Both DACs (Hifiberry / Audiophonics) should be nearly the same.

The only thing i have seen is a strange setting in your mpd.conf

audio_output {
name "snd_rpi_hifiberry_dac"
type "alsa"
device "hw:1,0"
mixer_type "hardware"
mixer_device "hw:hw:1,0"
mixer_control ",0"
mixer_index "0"
dsd_usb "yes"
auto_resample "no"
auto_format "no"
enabled "yes"
}

- Your DAC doesn't support hardware volume (same as Hifiberry DAC)
- "hw:hw:1,0" is wrong has to be "hw:1,0"

Please try to update to the lasted version.

Thank you, Frank. I'll try updating to the latest dev build (RuneUI is already up to date) before going away for the week end. I will also grab some more debug data along the way, starting with current working config, and working config post update.
About mpd.conf, where is that file, and is there a way to manually correct it?

Hi makfredo,

mpd.conf, where is that file, and is there a way to manually correct it?

The path is /etc/mpd.conf.
No you can't edit this file, because RuneAudio will change it back after reboot.
I think you did something wrong or not in the supposed order when configurating your system.

So, here's debug data from currently working setup (Linux Kernel 3.12.19-2): http://pastebin.com/gXc4AbwC
And here's debug data from working setup, post nightly build update and reboot: http://pastebin.com/RFs9gPHr
Switched back to latest kernel (3.12.26-1), no sound: http://pastebin.com/AS8AMYB0
—and back to Linux Kernel 3.12.19-2, with sound: http://pastebin.com/z5x6J1XB

I really don't know what is happening here… I hope you can figure it out, because I'm lost!

Hi makfredo,

i compared your debug data line by line and couldn't find anything special.
So sorry but i really can't help in this case.
It's really strange because with my Hifiberry DAC it works all just fine.

Very strange indeed… Could this be purely hardware related?
But the essential part is that I can use Rune anyway! Kudos for all the hard work you guys are putting into this fine piece of software!
