Ver 3.3.7 segfault on Raspberry Pi

[moodeaudio]

Hi,

Getting a segfault after compiling on a Pi. Below is a log of the compile session which looks OK to my eye. I'm using a .conf file from 3.3.6 version.

Thanks for this. I'll check it ASAP.

Would you be kind enough to post the configuration file, please?

// Sample Configuration File for Shairport Sync
// Commented out settings are generally the defaults, except where noted.
// Some sections are operative only if Shairport Sync has been built with the right configuration flags.
// See the individual sections for details.

// General Settings
general =
{
//      name = "%H"; // This means "Hostname" -- see below. This is the name the service will advertise to iTunes.
//              The default is "Hostname" -- i.e. the machine's hostname with the first letter capitalised (ASCII only.)
//              You can use the following substitutions:
//                              %h for the hostname,
//                              %H for the Hostname (i.e. with first letter capitalised (ASCII only)),
//                              %v for the version number, e.g. 3.0 and
//                              %V for the full version string, e.g. 3.3-OpenSSL-Avahi-ALSA-soxr-metadata-sysconfdir:/etc
//              Overall length can not exceed 50 characters. Example: "Shairport Sync %v on %H".
//      password = "secret"; // leave this commented out if you don't want to require a password
interpolation = "soxr"; // aka "stuffing". Default is "auto". Alternatives are "basic" or "soxr". Choose "soxr" only if you have a reasonably fast processor and Shairport Sync has been built with "soxr" support.
//      output_backend = "alsa"; // Run "shairport-sync -h" to get a list of all output_backends, e.g. "alsa", "pipe", "stdout". The default is the first one.
//      mdns_backend = "avahi"; // Run "shairport-sync -h" to get a list of all mdns_backends. The default is the first one.
//      port = 5000; // Listen for service requests on this port
//      udp_port_base = 6001; // start allocating UDP ports from this port number when needed
//      udp_port_range = 10; // look for free ports in this number of places, starting at the UDP port base. Allow at least 10, though only three are needed in a steady state.
//      drift_tolerance_in_seconds = 0.002; // allow a timing error of this number of seconds of drift away from exact synchronisation before attempting to correct it
//      resync_threshold_in_seconds = 0.050; // a synchronisation error greater than this number of seconds will cause resynchronisation; 0 disables it
//      ignore_volume_control = "no"; // set this to "yes" if you want the volume to be at 100% no matter what the source's volume control is set to.
//      volume_range_db = 60 ; // use this advanced setting to set the range, in dB, you want between the maximum volume and the minimum volume. Range is 30 to 150 dB. Leave it commented out to use mixer's native range.
//      volume_max_db = 0.0 ; // use this advanced setting, which must have a decimal point in it, to set the maximum volume, in dB, you wish to use.
//              The setting is for the hardware mixer, if chosen, or the software mixer otherwise. The value must be in the mixer's range (0.0 to -96.2 for the software mixer).
//              Leave it commented out to use mixer's maximum volume.
//      volume_control_profile = "standard" ; // use this advanced setting to specify how the airplay volume is transferred to the mixer volume.
//              "standard" makes the volume change more quickly at lower volumes and slower at higher volumes.
//              "flat" makes the volume change at the same rate at all volumes.
//      volume_range_combined_hardware_priority = "no"; // when extending the volume range by combining the built-in software attenuator with the hardware mixer attenuator, set this to "yes" to reduce volume by using the hardware mixer first, then the built-in software attenuator.
//      run_this_when_volume_is_set = "/full/path/to/application/and/args"; //  Run the specified application whenever the volume control is set or changed.
//              The desired AirPlay volume is appended to the end of the command line – leave a space if you want it treated as an extra argument.
//              AirPlay volume goes from 0 to -30 and -144 means "mute".

//      regtype = "_raop._tcp"; // Use this advanced setting to set the service type and transport to be advertised by Zeroconf/Bonjour. Default is "_raop._tcp".
//      playback_mode = "stereo"; // This can be "stereo", "mono", "reverse stereo", "both left" or "both right". Default is "stereo".
//      alac_decoder = "hammerton"; // This can be "hammerton" or "apple". This advanced setting allows you to choose
//              the original Shairport decoder by David Hammerton or the Apple Lossless Audio Codec (ALAC) decoder written by Apple.
//              If you build Shairport Sync with the flag --with-apple-alac, the Apple ALAC decoder will be chosen by default.
//      interface = "name"; // Use this advanced setting to specify the interface on which Shairport Sync should provide its service. Leave it commented out to get the default, which is to select the interface(s) automatically.
audio_backend_latency_offset_in_seconds = 0.0; // Set this offset to compensate for a fixed delay in the audio back end. E.g. if the output device delays by 100 ms, set this to -0.1.
audio_backend_buffer_desired_length_in_seconds = 0.2; // If set too small, buffer underflow occurs on low-powered machines. Too long and the response time to volume changes becomes annoying. Default is 0.15 seconds in the alsa backend, 0.35 seconds in the pa backend and 1.0 seconds otherwise.
//      audio_backend_buffer_interpolation_threshold_in_seconds = 0.075; // Advanced feature. If the buffer size drops below this, stop using time-consuming interpolation like soxr to avoid dropouts due to underrun.
//      audio_backend_silent_lead_in_time = 2.0; // This optional advanced setting, from 0.0 and 4.0 seconds, sets the length of the period of silence that precedes the start of the audio. The default is the latency, usually 2.0 seconds. Values greater than the latency are ignored. Values that are too low will affect initial synchronisation.

Fantastic, thanks -- it causes the segmentation fault. That means it should be quick to find. (Famous last words, I know...)

[mikebrady]

It's a logic error -- a combination I hadn't tested. If metadata support is included in the build but disabled in the config, it causes the segfault. I have a fix, but I'd like to check it with a clear head. I'll post it tomorrow, all going well.

To get around it for the present, don't set enabled to "no" in the metadata stanza -- comment it out or set it to "yes".

[moodeaudio]

Ok cool. I can confirm that with metadata = "yes" there is no segfault and everything else seems to work just fine :-)

[mikebrady]

Thanks Tim. Apologies for the sloppiness.

[mikebrady]

I just pushed 3.3.8rc0 in the master branch. It fixes that bug, I believe. If you tested it and let us know if it works, that would be great.

[Ircama]

I realized that mine was a different problem and still exists with 3.3.8rc0. It happens when the used Airplay client is the Android AirMusic app (also the trial version) and does not occur with an iPhone. The fix that I mentioned temporarily overcomes the issue.
