Three MythTV problems [SOLVED]

Message

I'm dangerously close to getting my MythTV HTPC fully functional. I even have a remote frontend (this PC) working well.

1) No sound. I know my soundcard (Audigy) is working because KDE chirps away whenever I start programs, minimize windows, start up, etc. However, as soon as I go into MythTV, I get no sound. I'm using /dev/sound/dsp and /dev/sound/mixer in MythTV. Permissions for those two are 660 root:audio. I can raise and lower volume in MythTV using the '[' and ']' keys--the OSD displays the rising and falling volume levels. MythTV was compiled with OSS support, a hint I got from another thread.

2) I cannot get my Radioshack 2116 remote control to work. LIRC is installed and lircd is running. I can run irw and then mash the keys on my remote and see the corresponding keypresses in irw, so I know the IR receiver and lirc are working. It's just that MythTV isn't getting it. I have a .lircrc symlink to .mythtv/lircrc-rs. Here's that file:

I initially set up MythTV and lirc to use the grey Hauppauge remote, and it worked. Since I changed my .lircrc to point to the Radioshack remote's file, it hasn't.

3) I'm using the PVR-350's TV-out (very nice!). It is capable of overscanning, and that is just great for actual television. However, the MythTV menus (the GUI) are getting lost past the edges of the screen just enough to where I can't make out some menu options. I'm fairly certain there's a way to correct this, but I'm not sure what settings I need to adjust and how.

Any answers would be greatly appreciated!

Hmmm- It's been a while since I've had to play with my .lirc setup, but I think that myth looks for lircrc at ./myth/lircrc. You can double check by running mythfrontend -v from the command line and watching for a warning about lirc.

Also, in my .lircrc, I also had prog=mythfrontend, instead of mythtv.

I'm not much help with the others though, sorry!

gcasillo · Post by **gcasillo** » Wed Dec 29, 2004 8:51 pm

I solved #3. MythTV goes looking for ~/.mythtv/lircrc, it doesn't bother with ~/.lircrc. I had a ~/.mythtv/lircrc-rs and ~/.mythtv/lircrc-hauppauge but no ~/.mythtv/lircrc. Fixed that. I now wield remote control power.

I haven't solved #2. Don't know what to try. Don't really care to battle for it ATM either.

#1, no sound. Still no sound. Can't for the life of me understand. My msp3400.ko is the one that came with ivtv not my kernel. I have MythTV setup to use /dev/sound/dsp and /dev/sound/mixer. They're there with the proper permissions.

I have sound in the files that are recorded, and I can play and hear audio from live TV on a remote mythfrontend, but I can't get any sound from the box with the PVR-350 in it and that is running mythbackend. I just don't get it. I don't have to run a Y-splitter from the L/R RCA audio jacks to my soundcard, do I?

In the meantime, I got an IR blaster working with my digital cable box. SWEET! I think I outdid myself there, but...no sound renders this setup useless.

I have MythTV with a pvr 250 and an audigy 2. I never had to run any cables to get sound to work, but I did have some trouble with OSS/ALSA.

I'd get sound with applications that were configured to use ALSA directly, but nothing else would work. I knew I had OSS emulation compiled into the kernel, too, so it was baffling. That's when I noticed that the modules weren't loading correctly at boot time. Restarting the alsasound service was enough to fix it every time until I got around to adding each module to /etc/modules.autoload.d/kernel-2.6 in the correct order.

You've said you compiled OSS support into MythTV, but is OSS emulation support loaded correctly? Check to see what modules are actually loaded when running the program. Of course, if I've got this backwards, and your problem is completely different, let me know.

Just a thought, but when I installed alsa, the sound board was muted. I think I used amixer to unmute it.

gcasillo · Post by **gcasillo** » Sat Jan 01, 2005 6:55 pm

I appreciate the responses. Everything is unmuted and jacked up 100%. Still no sound. I think I've tried restarting the alsasound service, but I'll try that later.

riskable · Post by **riskable** » Sat Jan 01, 2005 9:13 pm

If you're positive Alsa is working properly and you can hear sound using other Alsa-aware programs, make sure your MythTV front-end is setup to use Alsa.

Instead of /dev/dsp, manually type-in "ALSA:hw:0,0". You need to type it in manually (left and right arrows won't work).

You're using PVR 350? Are you using the TV-out from the PVR-350 to display on the TV? If so, then you need to use the sound out from the PVR350 also.. Its the PVR thats doing the decoding of the MPEG, so it just naturally uses its own sound device..

I have the opposite problem.. I wanna have MythGame running, but sound doesn't come through the PVR.. I haven't had to figure out if the sound device on the PVR is exposed at all to get it to work..

gcasillo · Post by **gcasillo** » Sun Jan 02, 2005 12:47 pm

Indeed, I am using the TV-out of my PVR350, and when I plug the red and white RCA audio cables into my television set, I get sound from it. I was just expecting to get audio fed to my sound card as well. That was my hope since I have a nice Audigy2 with the Inspiron 6.1 speakers and subwoofer.

I guess this means I need to run over to Radio Shack and pick up some sort of Y-cable to connect the PVR350's red/white RCA audio cables to the 1/8" line-in of my Audigy card. I think I've read about this sort of setup on the MythTV-users mailing list archive somewhere. I'll search around for that.

Thanks for the input, fellas.

garion911 · Post by **garion911** » Tue Jan 04, 2005 11:33 pm

Maybe you could use the out from the PVR350 into the IN on your sound card..

oggialli · Post by **oggialli** » Thu Jan 06, 2005 4:07 am

Thanks for the "ALSA:hw:0,0" tip. I was having a hard time figuring out why my +alsa -oss mythtv only showed me OSS entries (which obviously didnt work with no oss in myth)

Now I have sound working... joy

bruor · Post by **bruor** » Fri Mar 04, 2005 7:51 pm

to get sound on mythfrontend in kde, make sure that you have arts sed to die after 5 seconds or something extremely low

then lauch mythfrontend from the konsole window after waiting for the sound server to die...

in my experience arts hold onto the sound and myth cant get access to it...

on another note im having a problem with changing channels with an IR blaster, whenever i issue the change command, the playback gets extremely jerky and im lucky if the receiver catches 1 digit. if i just use the pc as a remote with no myth running the receiver changes channels fine...

im goign to try to add a little nice action in the channel change script when i get home, see if that helps it out any ...
