Long silence phases followed by short playing attempts than back to normal

[ste94pz]

Hi Mike, first of all I wanna congratulate with you for your great work on this software. I'm on Ubuntu 18.04 on a Minix Z83-4U with PulseAudio 12.2 running in system-mode and the latest shairport-sync compiled from git sources with this settings: --with-alsa --with-avahi --with-ssl=openssl --with-metadata --with-soxr --with-systemd --sysconfdir=/etc --with-pa --with-soundio --with-stdout --with-pipe --with-apple-alac --with-convolution --with-mqtt-client I can listen to about two songs without problems then I have a long silence phase followed by some audio chunks mixed with silence, then everything turns back to normal for other two or three songs. After that, the problem reappears. I always had this problem, even with older versions of shairport-sync and PulseAudio. The pc is connected to the router through gigabit ethernet and I'm streaming from an iPhone X connected through WiFi 5ghz AC near to the router. I have this problem with every AirPlay source, both iPhones and iTunes. Here you can find a piece of journal output when the probem appears.

Thank you in advance. Stefano.

[ste94pz]

Yes, of course. I post the log as a file because if I paste it here the eol characters aren't recognized, I don't know why. Since we are here, do you know why it says "Failed to load cookie file from cookie: No such file or directory" at the beginning? I think it's something related with PulseAudio in system-mode.

[mikebrady]

Thanks. I was interested to see if it was possible that the CPU wasn't fast enough to support soxr interpolation, but it certainly looks like it is, so that's not a problem.

Since the device is connected over wired Ethernet, WiFi can't be a problem.

Of course, the possibility is that there is some problem with PulseAudio. To see if that might be the case, would it be possible to direct the output to the ALSA backend, even temporarily.

If you run $ shairport-sync -h from the command line, you should get a list of the ALSA hardware devices, e.g:

...
Settings and options for the audio backend "alsa":
    -d output-device    set the output device, default is "default".
    -c mixer-control    set the mixer control name, default is to use no mixer.
    -m mixer-device     set the mixer device, default is the output device.
    -i mixer-index      set the mixer index, default is 0.
    hardware output devices:
      "hw:ALSA"
      "hw:IQaudIODAC"
...

If the problem persisted with the ALSA backend, then it is hardly likely that it's a PulseAudio problem. However, if the problem disappears, then it might be something to do with PulseAudio.

Other possibilities might be something odd about your network, or maybe the CPU or the network gets extremely busy from time to time. At the iPhone/WiFi end, is it possible that there is a common local source of interference, e.g. a microwave oven? (This should not be a problem at 5GHz, TBH.)

[ste94pz]

It's a minipc that I use as a home-server always on without the ui (I switch to only terminal mode with "sudo systemctl isolate multi-user.target"). When I need to use it as a normal pc, I start the ui with "sudo systemctl isolate graphical.target". The problem appears both in graphical and terminal mode. I use PulseAudio in system-mode because I need that multiple programs can access to the sound card and even when my user isn't logged in (when I don't use the pc, so in non-logged terminal mode, like an headless server). I don't know about the interferences, I don't have a microwave oven, I have around 11-12 wifi devices connected at 2.4ghz and 5ghz, and I have this problem with every device. I'll try to switch to ALSA and I'll let you know. Do you know if I can log some infos from PulseAudio?

[mikebrady]

That's interesting alright, and I can see the need for multiple access to the sound card. If it's not too difficult to switch temporarily over to ALSA, it should be possible to tell pretty quickly if the problem persists.

Regarding PulseAudio, I'm afraid I have no real knowledge of it – it seems to be a huge system.

[mikebrady]

There is nothing in the logs that looks alarming, just that, periodically and for some reason, the output falls far behind the input.

[mikebrady]

On the subject of sharing the audio output device, on Ubuntu 19.04 and maybe on recent versions such as 18.04 and 18.10, the ALSA device called default permits sharing. This is the ALSA device that Shairport Sync will output to if you don't enter any output device information. It's not ideal, since Shairport Sync works best with a real hardware device, but it might work better than using PulseAudio – worth a try, certainly.

[bedrin]

I've similar issue - silence for some time followed by few hiccups and then it returns back to normal. Happens probably once per 15 minutes or something.

I'm running Ubuntu 18.04 LTS but compiled Shairport manually (from tag 3.3.1, without soxr). It's old EEE PC 901 with x32 Intel Atom N270 1600Mhz

This is my config:

general = {
 name = "Marshall";
 statistics = "yes";
 log_verbosity = 3;
 interface = "wlp1s0";
};

sessioncontrol = {
 allow_session_interruption = "yes";
};

alsa = {
  output_device = "hw:0";
};

Tried a few versions but all give the same results. Any ideas what to try next? Appreciate any input!

After having put it on paper I realize now that it has something to do with my WiFi. I'm now checking my wifi power management settings - probably it's the case.

[bedrin]

So far it looks good after disabling Wi-Fi power saving as described in https://github.com/mikebrady/shairport-sync/blob/master/TROUBLESHOOTING.md

Stupid me - didn't read the instructions properly :(

Probably worth adding some kind of self-diagnostic either with printing to log (without enabling super verbosity) or even on install.

Sorry for hijacking this issue :)

[mikebrady]

No bother, thanks, and hopefully the problem is solved.
