Error while trying to run HRTF example from PyAL (File descriptor in bad state) on Raspberry Pi

QUESTION

Error while trying to run HRTF example from PyAL (File descriptor in bad state) on Raspberry Pi

Asked 2020-Jun-21 at 06:48

I am trying to experiment with HRTF audio spatialization using PyAL library on the Raspberry Pi https://github.com/NicklasTegner/PyAL/tree/master/examples/HRTF

PyAL depends on OpenAL. I have installed necessary dependencies using sudo apt-get install to ensure the library works: libopenal-dev libopenal1 libopenal-data libmysofa-dev libmysofa0 libmysofa-utils qt5-default alsa-utils alsa-oss alsaplayer-jack g++ gstreamer1.0-python3-plugin-loader gstreamer1.0-alsa

Additionally, I installed pyglet using: sudo pip3 install pyglet

All examples (3D audio, playback, efx, audiplayer, player) work except the HRTF example. When I try to run the HRTF example, I get the following error: AL lib: (EE) ALCplaybackAlsa_reset: snd_pcm_hw_params(self->pcmHandle, hp) failed: File descriptor in bad state

I know for a fact that this is being caused by PulseAudio not being present in the system (https://unix.stackexchange.com/questions/467193/error-while-running-the-gstreamer-example-on-development-kit-file-descriptor). So I installed pulseaudio and its corresponding tools (e.g. pavucontrol using sudo apt-get install pulseaudio.

After installing pulseaudio and rebooting, when I run that example, the example executes without error. However, I do not hear any audio output in the headphones. In fact, audio output from the entire system stops. I made sure the audio output is headphones from sudo raspi-config and alsamixer does show pulseaudio as a audio driver (when it is installed).

I am getting conflicting information from the Internet. The above link suggests using pulseaudio to mitigate the error (which is correct), whereas this link: https://www.youtube.com/watch?v=stvc7ehCWUU and https://raspberrypi.stackexchange.com/questions/1621/no-sound-output-in-vlc say to remove pulseaudio (which is also correct in the sense it brings my audio back but I can't run the HRTF example).

Any suggestions?

This is very odd, but I solved the problem by connecting a cheap external USB audio card (https://www.amazon.com/gp/product/B00IRVQ0F8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). Apparently, ALSA keeps control of 3.5mm jack and doesn't surrender control to Pulseaudio of that jack. Simplest solution is to use an external audio card.

If you just started with OpenAL and PyAL, it is strongly recommended that you read through the advanced sound support section of the documentation to understand, how OpenAL works in general. In any case, you can find the documentation at doc/html or online at https://pyopenal.readthedocs.io/en/latest/.
