What kind of TV card do you have? If it's one that provides an audio source to record from, does the audio source appear under pavucontrol -> Input Devices tab? (please attach "pacmd list" to this bug so I can double check this) If this is the case (and I suspect it is) then you need to load a "Loopback" module into PulseAudio to enable this. This is quite a simple process but there is no GUI to control this. Once you attach the pacmd list output I'll give you more exact instructions.

Summary: No sound => No sound in tvtime
Created attachment 153 [details] Output from pacmd list
Ok it's not TVtime or the TV card they are working fine. (hooked up headphones to the TV card itself) It seams that I'm not recieveing ang signal on the line input. I've attached the pacmd list as requested. Should I open a different bug report for this problem?

We can just keep this bug open for now. Do you use a loopback cable? i.e. plug in a cable between the output from the tv card and line in from the sound card? If so, there are two choices: 1. Enable h/w loopback on your card 2. Use software loopback inside PA If the former, there is not much in the way of nice UIs To do the former you should run "alsamixer -c0" and select the appropriate options (I'm not sure off the top of my head what they actually are tho' - possibly unmuting "line in") To do the latter you would run: pactl load-module module-loopback source=alsa_input.pci-0000_04_07.1.analog-stereo sink=alsa_output.pci-0000_00_14.2.analog-surround-51
Yes it has the loop-back wire. Ok I did the pactl load-module module-loopback I get nothing but static now. I also tried the "alsamixer -c0" and adjusted everything to the max without success. as for the source=alsa_input.pci-0000_04_07.1.analog-stereo & sink=alsa_output.pci-0000_00_14.2.analog-surround-51 It didn't seam to have any effect. If Iplug in my headphones into my tv card and I can here the sound with problem just not thru the line-in
Update: I installed The Alpha2 on a 2nd machine. It has sound with Tvtime Its a Dell Inspiron 530 Audio Chipset: Realtek ALC888 (7.1 Channel audio) The one that doesn't work is a home built PC with an ASUS M4A77D AM3/AM2+/AM2 AMD 770 ATX AMD Motherboard Audio Chipset: VIA VT1818S ( 8 Channel audio) South Bridge: AMD SB710 Could it be a driver problem with the on-board sound?
As I mentioned before, it's very much dependant on h/w. Some hard ware offers internal loopback, some does not. In PA we offer a software loopback system to allow things like this to work on such systems. Obviously any system based on software will introduce some degree of latency to the loopback which you may notice as a/v sync issues. If you know your system supports h/w loopback but it is not being heard, you will need to fiddle with alsamixer -c0 (where 0 is the card number of your primary sound card). In there you will find the necessary option (it's likely under "Capture" tho', so press F4 to activate that). You will likely have to unmute the Line In channel or similar). If the h/w does not support loopback you can use the software loopback as I described above.
Ok now I understand what your talking about, The real problem is that kmix only shows a single channel and I'm unable to add any others. Aumix at least show 4 channels just not the one in question. Thank I'll close this bug report and thanks again.

That's due to the pulseaudio+kmix integration, to see all the available channels, use: alsamixer -c 0 like Colin said, or load kmix this way from terminal: KMIX_PULSEAUDIO_DISABLE=1 kmix if you want to make this the default behaviour for kmix, add this line to your ~/.bash_profile: export KMIX_PULSEAUDIO_DISABLE=1
FWIW qasmixer (an Qt4 frontend (and more) for alsamixer) will be available in the repos soon.
