Re: [mythtv-users] ALSA Sound
I'm not familiar with the Chaintech AV710 - but I'm assuming it has alsa drivers?There are two ways to get alsa sound out your digital SPDIG plug in MythTV.1) If you have OSS compatibility turned on change your myth output device to /dev/adsp - this will use the OSS mixer to output PCM sound via the SPDIF Plug (this has worked for me on two via motherboards, a SIS based board and a PCI based MIDI/Sound Card)2. If you don't want OSS (pure alsa) change your Myth audio device to ALSA: iec958. This will not have a mixer (myth audio controls won't work), but you will get audio - change your volume on the receiver.DavidOn 31-Jul-05, at 1:41 PM, Brandon Rogers wrote: All, I know this has probably been talked about before, but since after 2 days of searching Google and trying “solutions” others have posted, I will come back and ask a question (which has probably already been asked 1000 times).

Re: [mythtv-users] ALSA Sound
Funny, that was one of the least painless parts for me. I got it working quickly and it worked great when I used that card. Look in Jarod's guide for some tips. But here are some rough tips. Make sure you disabled ARTS in KDE. Download gnome-alsamixer. Run gnome-alsamixer. Make sure the IEC958 box is checked. Adjust the volume control all the way up or all the way down for the IEC958 mixer. Test with aplay. Test with xine using the -aALSA and -HWAC3, flags (thats probably not the exact syntax read the man page). If you are using HDTV enable AC3 out in the mythfrontend setup screen. If you want to get more advanced follow the Mythtv WIKI howto for digital sound. When IEC958 is enabled you should see the port on the card light up.
