Default Daphile issue

Dear Phofman,


Thanks a lot for your answer and these informations.

I looked at sound/quirks.c at master * tiwai/sound * GitHub
The Dac is listed line 1392 ‘ case USB_ID(0x22e1, 0xca01): /* HDTA Serenade DSD */
May be I am wrong, but because my Dac is in this list and correctly identified by Daphile, DSF files natively support would work …
RIGHT ??

Daphile reads .dsf, because the functionality ‘convert DSD to PCM’ allows me to listen to my .dsf files once converted to PCM by Daphile (but the sound is less precise)

It is strange that ‘DSD over PCM’ and ‘Native’ options both fail.


To go further, I tried to have a look to /proc/asound/card2/stream0 file
I apologize for my poor knowledge in Daphile and Linux :
1. I understand from your mail that it is located in the Daphile file system
>>RIGHT ??
2. If so, how can I get access to it, knowing that once Daphile is started, the PC where Daphile runs seems locked ? I looked into the Daphile preinstallation key and the Daphile Iso file, but no such /proc/asound/card2/stream0 file seems to be there. I do not have any linux PC and the final key where Daphile is installed is not recognized by windows explorer.

And finally, in the case I could check this last point, would Daphile allow me to change any of its internal code or parameters to solve the issue ? And how without any Linux environment at home ?


Could you give me more information to investigate, and to fix the problem ?
May be my questions are stupid and the answer obvious …


Thanks once again.

Are you using the stock Daphile release or the Beta...?
Beta has ssh access......
Index of /firmware/beta

Username and password here....

You can use Putty from Windows pc or run a live Linux o/s from dvd or usb and use ssh from that.

Patch with that DSD-support quirk was posted to alsa-devel mailing list for inclusion in April 2018 [PATCH] ALSA: add more quirks for DSD interfaces — ALSA Devel . It is tagged for linux kernel 4.18 ALSA: usb-audio: add more quirks for DSD interfaces * tiwai/sound@f656891 * GitHub which was released two weeks ago.

Does daphile 18.07 use 4.14 kernel? Call for testers! Daphile - Page 28

Default Daphile issues

Hello Phofman, Drone7,



Now I understand why it does not work.

Many thanks for this additional information.

To solve it :

. I have installed the Daphile beta version.

. I downloaded “sound-4.18-rc1: sound updates for 4.18” from Release sound-4.18-rc1: sound updates for 4.18 * tiwai/sound * GitHub
And had a look at the decompressed files

. I also read the Web page where the patch is described
[PATCH] ALSA: add more quirks for DSD interfaces — ALSA Devel

I suppose I have to apply the patch or replace the 4.14 Kernel version by the 4.18 one.
Could you indicate more precisely where (on the installation key, the preinstallation one ? anywhere else) and how can I do that ?
(step by step, because my Linux knowledge is really ZERO)

If it fails, I will have to wait until the 4.18 kernel to be implemented in the Daphile new versions.


Best regards

Have you enabled DSD support in the plugins in "advanced media server" settings at the bottom of the settings tab?

Replacing a non-packaged kernel is not a simple task in regular linux distributions, let alone in an embedded distribution with read-only root filesystem like daphile.

I am afraid that is what you will have to do.

In the meantime you can check the new kernel does recognize your DAC by running a live distribution. That way you would learn a bit about linux too.

Since kernel 4.18 is brand new, very few distributions have it incorporated into their live iso image. I found only debex Exton DOWNLOAD | Exton Linux | Live Systems DebEX Barebone Linux 64 bit download | SourceForge.net

Default Daphile issues - Daphile plugin

Hello Triplefun,


If you were talking about the Kimmo plugin "Play back of DSD files (.dsf .dff) via your squeezebox", YES, I activated it two days ago.
With no results (I do not use squeeze box, and the plugin seems focused on squeeze box users)

Thanks for the proposal

regards

PS : I can't see other dsd plugin in the Daphile plugin list

Hello Phofman, Drone7,


I will follow your wise advises :

. Not to try a “no-simple” set up without knowledge and experience for that.
And quietly wait until Daphile developers implement 4.18 kernel version.
Anyhow, I can always listen to my DSD files using Windows foobar, even if I m sure the audio quality will be under daphile one, and that I must reboot the PC each time.

. In the meantime, I will little by little increase my understanding of Linux environment.
(it won’t be difficult, I am starting from scratch !)
I could always be useful.

I have to consider ‘the sunny side of the street’ :
Daphile allows me a better audio pleasure on my PCM files, which are 80% of my music.


Thanks a lot to everybody for the help and advises, may be I will get back to you later if my Linux knowledge seems to me later best enough to implement the modification by myself.


Best regards

I do not want to put you off, but adding new kernel to existing daphile installation is most likely very complicated. IMO the distribution image is built by some script from a preconfigured set of rules, very likely the gentoo catalyst tool Catalyst - Gentoo Wiki

If you do not have the configuration scripts, you cannot rebuild the image.

But again, you can always download another linux live CD/USB with kernel 4.18 and some clickable GUI environment, prepare a bootable USB (simple in windows), boot from it and check that stream0 file for DSD parameters of your DAC.
