Hi Again everyone,<br><br>I ended up finding a solution to my own problem. For some reason my MythTV install was muting my video 4 linux device. I still don't know why that was happening, but the following procedure fixed the problem for me.
<br><br>Once I start the mythfrontend, I Alt+Tabbed to my open shell and ran: "v4lctl volume mute off" without the quotes, of course.<br><br>This gave me my much desired sound. The sound was terrible though until I muted the CD line on my mixer to get rid of the echo, and increased the sample rate in the MythTV "Recording Profile" to clear up the reverb.
<br><br>I also notice, now that I have sound, my setup sounds much better with the mythfrontend device set as ALSA:default instead of /dev/dsp, again as expected.<br><br>Cheers,<br>Trevor<br><br><br><br><div class="gmail_quote">

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Hi All,</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have a Dvico Fusion HDTV 5 Lite
tuner card (Chipset bt878) and have installed MythTV 20.2 on a Fedora 8 box.
Ever since I went to Fedora 8, I can't get audio from the analog portion of this
card. HD audio works fine, of course, because of the audio encoded in the mpeg2
stream itself, but analog capture just doesn't work in
Myth.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">My card has an audio line out
plugged into the CD input port of my motherboard's onboard sound card. If I use
xawtv or tvtime to watch tv from this card, I get both picture and audio, but in
Myth I just get picture. Mind you, I had this same hardware and an earlier
version of Myth working fine on Fedora 6.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I know that Fedora 8 uses the new
Pulseaudio system, but I don't believe that is where the problem resides, as I
have removed the ALSA plugin for pulseaudio and tried several other things with
the ALSA mixer.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">My ALSA mixer setup is as follows:
CD capture is set to capture and CD playback is set to 100% volume. I've also
played around a bit with the AC-97 settings as several forums sites suggested
this, but to no avail.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Currently I'm just trying to get the
default Myth settings to work for me (i.e. make sound come from
/dev/dsp).</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">In mythtvsetup my analog card device
is set to /dev/dsp and in the mythfrontend setup the device is also /dev/dsp
although I've tried ALSA:default as well. Neither setup
works.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">To make things even more confusing
the following procedure works:</span></font></p>
<ol style="margin-top: 0in;" type="1"><li><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Turn on xawtv or
tvtime</span></font>
</li><li><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Mute the CD playback
line</span></font>
</li><li><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">aplay
/dev/dsp</span></font> </li></ol>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I do get slightly off sound as one
would expect using this method. My understanding is that if this works, then
MythTV sound should also work, but it doesn't.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Can anyone please help? This one is
driving me crazy?</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Thanks,</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Trevor</span></font></p></div>
