Running on Windows Subsystem for Linux with Pulseaudio working - /!\ Cannot open audio device. #685

Open ronilaukkarinen opened 5 years ago

Subject of the issue

Trying to run pianobar on WSL, Hyper terminal, Ubuntu 16.04. Getting it to run, but just skipping tracks with /!\ Cannot open audio device. message without any sound.

Your environment

config:

user = 
password = 

#control_proxy = http://98.102.88.158:8080
#control_proxy = http://208.114.192.126:8080

# https://www.us-proxy.org/
control_proxy = http://153.92.5.186:8080

fifo = /home/rolle/.config/pianobar/ctl
#audio_quality = high
#autostart_station = 829594236901097823

# http://www.gatherproxy.com/proxylist/country/?c=United%20States

#event_command = /home/rolle/.config/pianobar/events.py

Steps to reproduce

  1. Install WSL
  2. Install all dependencies and pianobar (followed this tutorial: https://gist.github.com/paulbaker3/2886698)
  3. Configure pulseaudio for Windows https://token2shell.com/howto/x410/enabling-sound-in-wsl-ubuntu-let-it-sing/ and testing https://community.mycroft.ai/t/experimental-mycroft-on-wsl-with-pulseaudio/5464

Expected behaviour

Songs should play normally with sound without errors.

Actual behaviour

Sound works when running paplay test.wav on Terminal. It just needs export PULSE_SERVER=tcp:127.0.0.1 to be run before. However, when running pianobar, it looks like this (debug on):

Alsa is currently not functional on WSL.

I don't think you need dev=default in your libao.conf. According to pa_simple_new you need pass a NULL to dev for default. If you set dev=default, a string "default" will be passed to pa_simple_new. see ao_pulse.c:266

ronilaukkarinen commented 5 years ago

Yeah, that's just one option I tried when desperately tried to get this to work. It's now removed from libao.conf but that doesn't improve the situation which seems to be stay the same regardless to that option.

Can you step into GDB, add a breakpoint at player.c:336 (the error message) and dump the value of the variable errno? It should tell us more about the failure.

ronilaukkarinen commented 5 years ago

GDB is not familiar to me as I'm not very experienced in testing and programming software as I'm only a server and web dev type of dude.

I have just installed gdb via adb. gdb --help works so I guess it's installed correctly. How to add breakpoint? (what that even means?) I presume I need to go to source dir where player.c is at or point to it somehow, but can you please provide me more precise steps on how to proceed, thanks!

PromyLOPh commented 5 years ago

Uh, that’s going to be tough if you’ve never used GDB before. Can you apply this patch instead? It should print the error number. https://gist.github.com/PromyLOPh/b294b0882c3bf942bf456dda0af19632

That is equivalent to AO_EOPENDEVICE, which means the driver is having some issue opening the device. It is likely this is an issue with libao on Windows Subsystem for Linux, so you might have to report it here and pray for someone to answer. Not much else I can do, unfortunately.
