Daphile - Audiophile Music Server & Player OS

Hm, it looks like a streamlined distribution, unsuitable for any diagnostics. All "noncritical" files/options are removed/disabled. That is one of the reasons I do not like this dumbed-down approach. Plug&play for any hw never works reliably (especially for USB audio which has received many crucial patches into the snd-usb-audio module recently). Having no troubleshooting facilities means dead end.

Yes, too bad.

I tried Volumio but it is not stable on my mini pc.

If you have better suggestion than Daphile for a x86 let me know

Try Snakeoil O/S Open source...

Thanks for the suggestion.....but it seems snakeoil doesn't support UEFI (UEFI Boot support) and my low cost mini-pc (not the best buy I ever made ...) do not have legacy mode. So, I didn't manage to boot

For checking your DAC IRQ rate options you can try e.g. live installer of ubuntu (or my favorite Mint Mate) and play anything with aplay. That distro certainly has all the debugging options enabled. E.g.

Code:

aplay -v -D hw:YOUR_HW_DEVICE --dump-hw-params -f YOUR_FORMAT  --period-size PERIOD_SIZE -c 2 -r 48000 /dev/zero

You can try various period size, check what the hw_params file in /proc lists, and what IRQ rate the given command produces.

Ok, so, I plug the Revolution Dac on my laptop (OpenSuse Leap 15.2).

When no music is played I have ~50 interrupts/sec and when music is played I have the ~7000 interrupts/sec.

Here is my hw_params

Code:

cat /proc/asound/Revolution/pcm0p/sub0/hw_params 
access: MMAP_INTERLEAVED
format: S32_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 44100
buffer_size: 88200

Here the lsusb -v

I do not understand this:

Code:

cat /proc/asound/Revolution/pcm0p/sub0/hw_params 
access: MMAP_INTERLEAVED
format: S32_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
[B]period_size: 44100[/B]
buffer_size: 88200

and this:

Code:

aplay -v -D hw:Revolution  --dump-hw-params -f S32_LE [B]--period-size 8[/B] -c 2 -r 48000 /dev/zero
...
  [B]period_size  : 8[/B]
  period_time  : 166

The second version would clearly require IRQ every microframe (125us vs. period time 166us). How did you attain the hw_params dump with period size 44100? My 2cents is playback through pulseaudio which configures very long periods when running in timer-scheduled mode (tsched = 1).

Try aplay with similar large period size and then measure the IRQ rate.

Brunhylde · 2020-09-24 6:01 pm

Oh, ok, got it, my mistake.

For period-size=8

Make more sens ?

phofman · 2020-09-24 7:33 pm

Very good, now only the goal missing - checking IRQ rate for the larger period. Thanks for testing.

Brunhylde · 2020-09-25 5:00 pm

No, no, thank you !

So, with no music, irq rate :

Code:

“sec 1: 71”
“sec 2: 87”
“sec 3: 63”
“sec 4: 63”
“sec 5: 63”

with aplay -v -D hw:Revolution --dump-hw-params -f S32_LE --period-size 8 -c 2 -r 48000 /dev/zero

Code:

“sec 1: 8037”
“sec 2: 8007”
“sec 3: 8053”
“sec 4: 8023”
“sec 5: 8007”

and with period-size=65536, same :

Code:

“sec 1: 8008”
“sec 2: 8023”
“sec 3: 8049”
“sec 4: 8040”
“sec 5: 8022”

I've installed the latest Daphile version daphile-20.08-i486.iso and I'm having problem with the cover art display. Upon installation, the cover art files (folder.jpg) are all correctly displayed. From the second use of Daphile onwards, every single album shows the same cover art picture. Anyone knows what happens?

Another observation is that the stop/start between tracks is very noticeable. This is okay for non-concert albums but the interruption can be quite distracting. Anyone has this problem as well?

DRONE7 · 2020-10-01 6:27 am

You're using the i486 version so perhaps you can provide the specs of the machine you have installed Daphile on ?

(could be a resource issue but without any info it is hard to say)

shsoh · 2020-10-01 6:36 am

Hi, I'm running on an Intel Atom N270 chip which I believe is 32 bit with 1Gb ram.I tried using the 64 bit version but it doesn't proceed with the installation.

DRONE7 · 2020-10-01 7:41 am

I've not had much success with less than 2GB storage and 2GB ram.
Several (Thin-client) installs with those specs and the 32 bit version work fine.

Are you able to increase the ram on your Atom board ?

SRMcGee · 2020-10-02 12:43 am

Folks:

I suspect my server's motherboard is fried, but would appreciate your opinion. The motherboard is an ASRock N3050B-ITX, which has been in service for about 4.5 years and has worked fine during that period. RAM is 4 Gb. The Ethernet connection at the server is via a powerline extender. The server is plugged into a Furman AC-215 surge protector (but not the powerline extender). A month or so ago, I went away for a long weekend and shut the server down. Upon my return home the server refused to boot up -- it would hang at the first screen (see photo). I installed a new thumb drive (on which Daphile is loaded) but did nothing more, and a couple of days (and many attempts) later it booted successfully. I assume the original thumb drive was not the problem, since the server would hang before loading Daphile. A few days ago we had a power surge and around that time the server again went offline; the result is the same as before (again, refer to the photo). I don't know if the surge is relevant, but them's the facts.

So is it likely my motherboard (or RAM) is toast? Is there another plausible explanation?

If the motherboard needs replacing, any suggestions? The standoffs in my server case (which I'd like to continue using) are arranged for ITX motherboards. I could always drill new holes and install standoffs, but given a choice would choose not to.

Thanks in advance for the feedback.

Regards,
Scott

DRONE7 · 2020-10-02 4:31 am

4.5 years is a long time for that poor little Bios Battery...
Before all else spend a dollar and replace it with a new one..

If you can boot into the bios screen currently then make a note of the settings on each tab as a quick reference if you need to reapply them after battery replacement.

Cheers,
bob

phofman · 2020-10-02 8:02 am

There are many discussions found by google about BIOS boot being stuck at stage 99 (presumably SuperIO initialization). Reconnecting USB keyboard/mouse, resetting BIOS (CMOS battery), all sorts of trial/error/sometimes success stories.

...as the man says @Drone7...

If you don't have any TEST Standalone media (CD-ROM or USB flash memory stick) you can create a USB 'test' environment standalone tool by building a LIVE USB bootable disk... I'm just giving you a suggestion here out of many: Linux Mint Installation Guide — Linux Mint Installation Guide documentation
You can run Mint from the stick and/or you can install it on your 'server' machine (this way you'll find out whether the HDD might need replacement)... Draw your own conclusion.

Hi All, does anyone experienced track seek issue, when playing from Tidal? When to click somewhere in the middle of track seek bar, it just stuck for second and stops. So it`s impossible to navigate through track, just listen from beginning till end. I have tried few x86-64 releases and betas on Lenovo T series laptop with same issue. I have squeezebox Tidal plugin.
No such issue when playing from HDD, so it`s like Tidal plugin bug?..

SRMcGee · 2020-10-02 1:29 pm

Drone7 & phofman:

Twas the battery. You guys are good.

Many thanks,
Scott
