If audio works in mythtv but nowhere else it's obvious it's not a muting, hardware or whatever...<div><br></div><div>You just need to configure the OS audio settings to use the same audio card as you've set in myth.</div>
<div><br></div><div>This is done using whatever UI the system offer, or defining a global /etc/asound.conf and setting the default device to be whatever you've defined in myth, without the "ALSA:" part</div>
<div><br></div><div>I would create a dmix plugin, so more than one application can use the audio device at once.</div><div><br></div><div>You said HW:0,3 worked for you. So in your asound.conf or tlocal .asoundrc you add:</div>
<div>pcm.!default {</div><div> type plug</div><div> slave.pcm "dmix:0,3"</div><div>}</div><div><br></div><div>That's it.<span></span></div><span></span>
