Heh, I never thought of it as sounding like a motor boat, but now that you say it, it really does. I have this issue as well on a nForce 630 chipset. It does only happen occasionally so I just thought it was the cheap internal sound card. Now that I think of it, this also happened in Windows every once and a while, but I narrowed that
down to bad drivers. I removed the bad drivers and it went away.<br><br>One thing I have noticed, it only does it on DTS tracks (DD/AC3 seem fine).<br><br>I have noticed it does it in Myth more than anything else. I installed XBMC, and have had 0 audio issues since I tried it. DTS crackling is totally gone, so it the motor boating wind down.<br>

<p> Hi,</p><p><br>
</p><p> I wrote to the list a while back about a motorboating noise I sometimes get. At the time I hadn't isolated when it happens, and couldn't stop the behaviour without a complete cold reboot (unloading modules doesn't help).<br>
</p><p><br>
</p><p>I use digital passthrough with my onboard Nforce4.</p><p><br>
</p><p>The problem occurs when I abruptly end playback from the internal player, it's as if the audio stream isn't correctly ended and the audio hardware goes into a feedback loop. Using mplayer or xine, I don't have this issue, so they must have a mechanism for rounding off the audio stream.I also notice that the clicks and pops when I chance audio codec or format are much, much queiter in mplayer and xine than using Internal.</p>
<p>The solution to the problem is also much simpler than I thought. I just have to feed the sound system a new stream, and the loop stops.</p><p><br>
</p><p>Does anyone know if this is a known issue?</p><p>Can I end every playback from Internal by playing a short, empty audio stream? If so, how?</p><p><br>
</p><p>Cheers!</p><p><br>

I do not know if this is a known issue and I have a little old version of Myth, Mythbuntu 8.04 LTS. I have done only a few updates and only to solve a specific problem. If you find out there is an update to fix this please post in this thread.</div>
