there is no emu10k1 use flag in alsa-firmware, it's not contains the emu directory, but original alsa emu firmware-s works great. Reproducible: Always Steps to Reproduce: emerge -av alsa-firmware there will be no /lib/firmware/emu dir Actual Results: from /var/log/messages: firmware: emu/emu0404.fw not found. Err = -2 workaround: after emerge alsa-firmware: get the alsa-firmware source tarball from alsa page with the same version number, compile it (no make install), then copy .fw files to /lib/firmware/emu. modprobe alsa drivers, restart service, and listen to music with your emu card.
You're right, I never would have noticed that. Thanks for the bug report, fixed in alsa-firmware-1.0.20-r1.ebuild
