I am using a Winfast Leadtek TV 2000 XP card and TVTime 1.0.2 to watch analog TV. The TV card's sound output is hooked up to the CD-in of my mainboard (MSI Intel X58 Platinum).

Just recently I managed to get ALSA to correctly recognize the CD-in (see How do I enable CD-in?).

Now I would like TVTime to adjust the ALSA CD slider when turning the volume up and down in TVTime. However, TVTime refuses to do this and I always have to use alsamixer to control the volume.

I have tried different settings for the MixerDevice setting in the tvtime.xml configuration file as suggested e.g. in https://askubuntu.com/a/217462/9598. When using this value, this is the output when running TVTime:

Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/chrisipk/.tvtime/tvtime.xml
ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL 
mixer: attach error: No such file or directory
mixer: Can't open mixer , mixer volume and mute unavailable.

This is what I currently have:

<option name="MixerDevice" value="default/cd"/>

This is the output when running TVTime:

Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/chris/.tvtime/tvtime.xml
mixer: find error: Success
mixer: Can't open mixer default, mixer volume and mute unavailable.
mixer: Can't open device default/cd, mixer volume and mute unavailable.

The current setting seems to be somewhat right as the output no longer complains about missing a file or directory and contains "find error: Success".

What do I need to do so that TVTime can adjust my CD-in volume?

I found the answer to a very similar question: https://askubuntu.com/a/51574/14220

This worked for me. Here is what the relevant line in my tvtime.xml now looks like:

<option name="MixerDevice" value="hw:0/CD"/>

Note that this is case sensitive, using a lowercase "cd" as suggested by the tvtime.xml man page did not work!
