After doing a lengthy troubleshooting for my TV tuner to be recognized by LinuxMce/MythTV
http://forum.linuxmce.org/index.php?topic=5545.0
the problem that I am currently encountering are the following:
1. Live TV is fuzzy - but still can see the show. (To isolate the problem, since I am thinking it might be my cable provider's issue, I booted my system using Windows Vista MCE - that is same hardware, and Live TV in Vista is very very clear). Thus, I am still having problem with the driver.
Is there any other setup I need to do? I did some change in MythTVbackend and Mythtvfrontend.
2. I have no sound on Live TV...Other features of Linux MCE like watching DVD, music do have sound.
I already followed some of the instructions from these sites:
http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound
http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIF
Since I am using Digital Coax/SPDIF for my sound system (solved this problem based on this http://forum.linuxmce.org/index.php?topic=5539.0)
Any help or idea? Thanks.

Any idea on what to put in the MythTV frontend?
On Mythfrontend Utilities/Setup->Setup-General go to the Audio page and set your audio device as
Audio output device = ???
Passthrough outputdevice = ???
Enable AC3 to SPDIF passthrough check
Enable DTS to SPDIF passthrough check
Thanks.

I have checked also that:

I also have found these sites, but cannot help my "sound" problem. Having a fuzzy TV reception at this time is fine, as I am planning to change my TV tuner. But for the spdif, I need to make it work since my amp is connected via spdif coax.

Thanks. But the above did not seem to be applicable since I have only 1 TV tuner (wherein I also disabled the cx88 snd): http://forum.linuxmce.org/index.php?topic=5551.0
This thread detailed on how I installed the tv tuner. My DVD, music, all worked properly, except MythTV Live TV. Thus, Intel HDA is working perfectly but not in Live TV.
linuxmce@dcerouter:~$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xc6efc000 irq 16
linuxmce@dcerouter:~$ asoundconf set-default-card 0
linuxmce@dcerouter:~$
It only showed that I have only 1 sound card. But still I tried asoundconf to be sure.
