[Buildroot] Buildroot with Alsa-Lib Question

[Jon Ambrose]

Hi all,

 

I hope you can help.

 

Basically I am trying to get Flite 1.4 (Text synthesis application) working
on my embedded Arm IGEP v2 Platform, using Buildroot.

 

For this to work and my applications to cross compile, I need
libasound_module_pcm_pulse.so located in /usr/lib/alsa-lib/ however nothing
like that appears. This library I think is part of something called Pulse
Audio. Which I don't think Buildroot offers does it?

 

Does anyone have any advice or suggestions?

 

This project is for my Undergraduate course, and currently I just feel like
I have hit a brick wall.

 

Cheers,

 

Jon

As far as I understand, libasound_module_pcm_pulse.so is the ALSA
plugin that re-injects the sound output into PulseAudio. It allows
application written on top of ALSA to work nicely with PulseAudio. We
don't have a package for PulseAudio at the moment, but for your
project, you probably don't need it. You should tell your Flite
application to directly talk to ALSA devices, and not configure those
ALSA devices to loop back into PulseAudio.

Regards,

Thomas
