I'm running Chakra Linux, and found myself needing to play some audio CDs. So I installed Kscd. The only thing showing up in the device notifier is Play Audio CD with Kaffeine, so I right-clicked the notifier and chose Settings -> Device Actions -> Play Audio CD with KsCD -> Edit. I changed all the settings there to match the ones in Play Audio CD in Kaffeine. But no good; KsCD still does not show up as an option when I insert a CD. What gives?

BTW, here's is the contents of /usr/share/apps/solid/actions/kscd-play-audiocd.desktop:

Code: Select all

[Desktop Entry]
X-KDE-Solid-Predicate=[ StorageVolume.ignored == false AND OpticalDisc.availableContent == 'Audio' ]
Type=Service
Actions=open;

[Desktop Action open]
Exec=kscd -s
Icon=kscd


Unless I misunderstand the syntax, this file should do the job.

If you run the following, do you get any results?

Code: Select all

solid-hardware query "[ StorageVolume.ignored == false AND OpticalDisc.availableContent == 'Audio' ]"

No output.

This indicates that Solid is not detecting the device as a CD. Solid relies on underlying frameworks (HAL in 4.5 and earlier, and UDev in 4.6 and later) to provide this information.

What output do you get from "solid-hardware list"?

That seems strange to me, since the device notifier does give me the option of "Play Audio CD with Kaffeine". But anyway:

Code: Select all

With the previous command, did you have a CD in the drive at the time? (the solid-hardware --query command)

Also, try comparing the Predicate in the KsCD desktop file with the Kaffeine file.

might your problem be that kscd is not properly configured to be used in the notifier widget now that hal is replaced with udev? I only say this because iirc Audex is no longer an option when I insert a cd, though it did in 4.5.

so I created a new device action that looked like this based on the Amarok option

and it opens the cd in KsCD as it should but my kscd seems borked so though it displays the track it doesn't play it - weird

Yup, something's got to be wrong with Kscd. I wonder what else will play cds...

Found a cure! Changed:

Code: Select all

X-KDE-Solid-Predicate=[ StorageVolume.ignored == false AND OpticalDisc.availableContent == 'Audio' ]

to:

Code: Select all

X-KDE-Solid-Predicate=OpticalDisc.availableContent & 'Audio'

As of right now I can't find any way to do this as a user with the GUI tools.

There is nothing wrong with KSCD. There is however something very wrong
with KDE 4.6x device notifier. It doesn't recognise any audio programs
when you insert an audio cd except amarok, which won't even play audio
CDs. No matter what you do in the settings, nothing changes!!

@2handband: In the Device Actions edit action dialog, see the drop down below "Value name" which can be changed to "Contains" which will cause it to generate the "&".

@bcooksley

I had the same problem as secondhandband.
High time to rewrite the Help File!
