HOW-TO: Getting the WinTV-HVR 950 to work WITH AUDIO in ANALOG Mode

[punkrawker82]

I was building a MythTV box for a friend and was having issues with the AverMedia M-150 D they had installed. I had audio and video working in analog with that card, but the framerate was horrible. It was absolutely unwatchable. My friend informed me he also had a Hauppauge WinTV-HVR 950 I could try, so...


I plugged it in

Performed a fresh install of Mythbuntu 7.10

Followed the Fiesty Fawn instructions located here:

And I couldn't get audio to work with analog using the WinTV-HVR 950. So, I went back to a site I had looked at for the Avermedia M-150 D which discussed the index of audio devices located here:

http://mythtv.org/wiki/index.php/PCI_TV_audio

I remembered having to manually set my cx88 device to an index of 1 when working with the avermedia tuner. But in the case of the WinTV-HVR 950 I needed the EM28xx to have an index of 1, so...

I ran the command

sudo cat /proc/asound/cards

Sure enough, my audigy sound card had index 0 (which it should), the cx88 had index 1, and the EM28xx had an index of 2. I needed to flip the cx88 and EM28xx so that the EM28xx has an index of 1 and the cx88 has an index of 2. From the audio site it stated the EM28xx uses the snd-usb-audio module. You can control what index an audio device receives by manually editing /etc/modprobe.d/alsa-base

I ran the command

sudo nano /etc/modprobe.d/alsa-base

The WinTV-HVR 950 uses the snd-usb-audio module. So I located the line:

options snd-usb-audio index=-2

and changed the index of -2 to an index of 1. I also changed the index of my cx88 based avermedia tuner from an index of -2 to an index of 2. I then saved my chnges and rebooted.

After I rebooted, I ran the mythtv backend once again and made sure the setting for my Audio Device within the Analog Capture Card Setup was set to /dev/dsp1 as we set the EM28xx/snd-usb-audio to use index 1.

In my MythTV frontend General settings I'm using the ALSA Default.

There you have it, the WinTV-HVR 950 setup in analog with working Audio and Video.:-D

Let me know if it works for you guys!

This thread probably isn't checked anymore, but could you give some more detailed instructions on how you did this?
For some reason on mine I only have the one sound card in my system. I don't have a /dev/dsp2 for my HVR 950, even though analog video works fine; no sound whatever I try.

I still check from time to time :)

In your case your normal sound card should be set to index 0, and your HVR 950's sound should have an index of 1.

Run:

sudo cat /proc/asound/cards

And determine if this is the case. You should see your normal sound card and your HVR 950's sound found. It has been a while and I don't have the system to check as it was my friends, but the HVR 950's sound should be something like "EM28xx". Run:

sudo nano /etc/modprobe.d/alsa-base

Find the line for the HVR 950 sound module. It should be:

options snd-usb-audio index=-2

Change this line so that it becomes:

options snd-usb-audio index=1

Reboot and then run the mythtv backend once again and make sure the setting for my Audio Device within the Analog Capture Card Setup is set to /dev/dsp1 since you set the EM28xx/snd-usb-audio to use the index of 1.

Basically make sure the /dev/dsp number in MythTV is set to the same number as the index you manually set in /etc/modprobe.d/alsa-base. When I didn't manually define the index the different sound devices would be assigned random indexes each boot. The -2 that they have by default seems to be like a first come first serve basis.

It should work fine with MythTV frontend General settings set to use ALSA Default.

I hope that helps :)
