From their mail list: > We are trying to port sflphone daemon on arm omap3530. How > can we remove pulseaudio dependency as omap 3530 uses ALSA? This would involve adding a --disable-pulseaudio option to configure.ac, modifying the corresponding Makefile.am files, and hiding the call to "new PulseLayer" in audiolayer.cpp with an #ifdef. Patches welcome. I would try to make such a patch myself, but I am afraid it is a bit beyond my skills.
This is done upstream: https://projects.savoirfairelinux.com/issues/12069 I assume it is in the 1.2.0 release.
From the sflphone mailing list (no, this was not me - I already knew that): "> The Gentoo ebuild seems to require pulseaudio. Is that a mistake? You can disable pulseaudio and use only ALSA."
Just received confirmation that this feature was available as of 1.2.1.
Implemented in latest ebuild.
