Precise [1] filed a deletion request for rtaudio5-exp [2]: Indeed, it is entirely possible to completely remove this package without consequences, since it is outdated and not actual. sdrpp package is now supported both rtaudio 5 and 6. So this dependency is absolutely unnecessary. [1] https://aur.archlinux.org/account/Precise/ [2] https://aur.archlinux.org/pkgbase/rtaudio5-exp/
