Its been reported: https://bugs.gentoo.org/645196

Maybe add that what you noticed about crypt / cryptsetup USE stuff?

[gentoo-user] udisks doesn't find libblockdev

[tuxic]

Hi,

got a problem this morning...

Calculating dependencies... done!
 * Dependencies could not be completely resolved due to
 * the following required packages not being installed:
 * 
 *   >=sys-libs/libblockdev-2.14[crypt] pulled in by:
 * sys-fs/udisks-2.7.5
 * 
 * Have you forgotten to do a complete update prior to depclean? The
 * most comprehensive command for this purpose is as follows:
 * 
 *   emerge --update --newuse --deep --with-bdeps=y @world
 * 
 * Note that the --with-bdeps=y option is not required in many
 * situations. Refer to the emerge manual page (run `man emerge`)
 * for more information about --with-bdeps.
 * 
 * Also, note that it may be necessary to manually uninstall
 * packages that no longer exist in the portage tree, since it may
 * not be possible to satisfy their dependencies.

I read the oracle as follows:

udisks wants libblockdev version egual or greater 2.14 with "crypt"
USE flag set.

libblockdev itsself is installed with version 2.15, which is "equal or
greater 2.14" and with cryptsetup set...which is not "crypt".
There is no USE flag "crypt" with libblockdev.

H...

What next?

... however it is entirely possible that I messed something up that's
related to the profile switch.  Seeing as this is my first profile
upgrade I wouldn't be surprised to find that I've horribly broken
something.

For the record, I tried to install app-crypt/yubikey-manager-qt, which
pulls in qtdeclarative as a dependency.

I'm rebuilding the 107 packages that revdep-rebuild reported (no idea
how that happened) right now, and I'll see if that fixes things.  No
doubt this will be one giant learning experience for me :)

Thanks!

Re: [gentoo-user] mpv: no sound anymore...?

I don't have any particularly concrete ideas because the error log isn't
very descriptive, but I have several things you can try that will give
us more info/may help pinpoint the issue.

You might want to post the contents of your /etc/asound.conf and your
~/.asoundrc as well as maybe checking the contents of /usr/share/alsa if
there's anything still referencing pulseaudio in there. Maybe also a
qcheck media-libs/alsa-lib to check if any of the default config files
have any changes in them (you can also diff the output of qlist alsa-lib
and find /usr/share/alsa).

You might also want to check your mpv.conf if you have change any of the
audio settings there.

You can try running mpv in verbose mode (-v) to see if that prints any
more relevant information and also try using any of the other (alsa)
audio-devices listed by --audio-device=help. You could also try setting
--audio-samplerate=48k and try enabling/disabling alsa resampling with
--alsa-resample=yes/no.

mpv's verbose mode will probably give more info as to why it's trying to
open alsa, but I don't know enough about jack to give any useful ideas
here.

What samplerate does that generate sound at? 48k or 44.1k?

I'd start by running 'alsactl init' to (re)initialise alsa and see if it 
reports any errors.
