No sound capture
I'm loving Mythdora 12.23!
All the problems that I have had with it for the last few years have disappeared!
My current Mythdora Box is an AMD Duron 1800, 512MB DDR, 160GB ATA HDD.
Capture cards are a Compro DVB-T300 and a Compro DVB-S350.
Today while doing some shopping today, I saw a Compro DVB-T220 in a shop very cheap, so I bought it blindly without finding out if it would work with Fedora.
Unfortunately there is no DVB support for it under V4L.
I waited two years to get support for my DVB-S350 card, so I when someone finally cracks it and gets it working with V4L-DVB, that will be a bonus.
I have discovered that the analogue capture side of the card works, (it appears as a Compro DVB-S300/350 under V4L), but it doesn't support audio capture.
So I have spent the day attempting to get it to capture a satellite set top box.
The card works fine with Mythdora capturing a picture off it using V4L, but I cannot get it to capture the audio.
Currently the audio is set for ALSA:Default and the audio is plugged into the line-in of the default sound card.
I have tried it with the onboard ALC200, and a few different Sound Blasters, but all of them will not capture audio under MythTV.
Currently I am using an old SB Ensoniq that used to work fine under Mythdora several years ago.
When that didn't work, I started doing some home work.
My tests are so far:
- When line-in is un-muted on ALSAMIXER play back, I can hear the audio.
- I have installed Audacity which is defaulted to ALSA:Default, that can record OK.
- 'arecord -t wav -r 44100 -c 2 test.wav' records the correct audio and plays back OK with aplay.
What am I doing wrong?
This is very frustrating!
My current build of Mythdora is stock without any additional ticks for support of my NVidia 6200 or additional repositories.
The audio capture problem was evident after a clean build and is still there after a 'yum update'
