Hello,
I can't connect a pa_context to the PulseAudio server. Can anyone help?
I've been trying to use the async API to connect to a source which has
been setup by a PulseAudio CLI script.
When I use the script via the --file=<filename> argument to pulseaudio,
then run my programs that use the API to connect to the source then
everything works just fine.
When the CLI script is run on another machine as part of the start-up,
then the program that uses the API (also on the same machine) always
fails on the pa_context_connect() call, with "Connection refused" being
the result of pa_strerror(pa_context_errno(context)). The context was
successfully created using a pa_mainloop_api * returned from a
successfully created pa_mainloop.
I've attached the syslog extract for the session. The PID for the
pulseaudio process is 2733 (which is also what's in
${XDG_RUNTIME_DIR}/pulse/pid) from "ps auxf". The program attempting to
connect the context with the server exits because of the failure, but is
restarted every 30 seconds (with progressively increasing PID). All the
relevant processes are owned by the same user. When I ssh to the
machine as the same user, I can connect with pactl. "pactl list short
sources" lists all the sources I expect to see, and "pactl info" gives
the following output:
Server String: /run/user/1001/pulse/native
Library Protocol Version: 30
Server Protocol Version: 30
Is Local: yes
Client Index: 9
Tile Size: 65472
User Name: operator1
Host Name: mm2
Server Name: pulseaudio
Server Version: 8.0
Default Sample Specification: s16le 2ch 44100Hz
Default Channel Map: front-left,front-right
Default Sink: audio_out
Default Source: alsa_output.pci-0000_02_00.1.hdmi-stereo.monitor
Cookie: 68bb:73b4
The platforms are ubuntu 16.04. The call that fails is:
result = pa_context_connect(context, nullptr,
PA_CONTEXT_NOFLAGS, nullptr);
Cheers,
Steve Wawryk
