Even if you can't power up, can you just drop your volume to 0 prior to shutdown?
I just powered up and shutdown with the speakers on (low volume, of course). The sound mine makes is not even half a second and sounds similar to what you describe in terms of pitch - like an Atari laser sound or something. The power supply is a bit overkill - Seasonic 450 watt (Pentium MMX 200 on i430FX mobo). I had an SB16 in it (noise blaster) until I started working different sound cards over to see how well things sounded. I too tried out the YMF719 after all the talk here on vogons.
It is possible that changing capacitors would help your situation <shrug>. It could also be just how the card powers down (don't have the problem with other cards). I am not concerned about my situation because I power all audio down prior to computer. I suppose if you wanted (and this is probably a bit annoying), you could experiment a bit and lower all of your volumes in the mixer prior to shutdown to see if it is actually something outputting a little extra sound from your mixer at the time power is cut. If so, you could create a batch file for setting your volumes to 0 prior to shutdown. If not, the circuit is going to output that noise regardless.
Although I appreciate the quieter noise level and general improvement in tracker-style sound having switched from the SB16, I am not all that impressed with the YMF719 so far.
Interesting... we're both using overkill Seasonic power supplies. If yours is a newer Active-PFC type (mine is a 350ET) that could be possible lead. As for just turning down the volume, I can, but the other quirk of this mini amp is that it is a digital volume dial. It just keeps rotating and there is no volume indicator, and in fact most of the time it isn't silent when turned all the way down. Had I known this, I wouldn't have purchased it. Still, for $35 it has a high build quality and plenty of power (its a TDA7492 based amp)... just annoying to use for someone like me that prefers reliable, manual, analog controls.
Honestly, while the noise is annoying, I'm more concerned about what is causing it. If something electrical is doing it, it can't be healthy for the sound card or the rest of the computer. Whatever it is, its causing an astronomical amount of non-random noise to make its way to the line-out on my sound card.
As for the card itself, I haven't gotten to do a whole lot with it yet, but I haven't honestly noticed anything that it is doing better than my CT2940 (with real OPL3). I'm using a separate card for MPU401, as mentioned, so the main benefit (non-buggy MPU401) is lost right there.
I don't like that the mixer\setup program is quirky, but it does give a lot of options and its possible to avoid the quirks somewhat by just editing the config file manually.
Now for some blitting from the back buffer.
