The past (and first) week working on the audio stack, sponsored by the FreeBSD Foundation, I: - Set up my development environment; a VM image running -CURRENT in bhyve with PCI-passthru enabled to do all of the driver (kernel generallly) development in the VM. - Wrote a small series of patches for vmrun.sh: https://reviews.freebsd.org/D43269 https://reviews.freebsd.org/D43270 - Modified the snd_uaudio(4) driver to provide information about the sound card (manufacturer, model and attached driver), as opposed to the current generic "USB Audio" string, so /dev/sndstat and programs like mixer(8) can output more useful information about USB audio devices. https://reviews.freebsd.org/D43347 - Submitted a patch to update (and unify) the description format for all sound devices, since some of them haven't been touched for years. https://reviews.freebsd.org/D43349 - Implemented device_set_descf() , a printf-like version of device_set_desc(). https://reviews.freebsd.org/D43370 - Was preparing a few more smaller patches. - Started looking into possible solutions to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194727 also mentioned in the first paragraph of the BUGS section of the snd_uaudio(4) man page.
