One of Roxie’s favorite past times is removing the innards (squeakers, fluff, etc) from stuffed animals. She only plays with those she is given, but once she has one she quickly sets into it. Throughout the week I’d find her taking the toy and pressing it into my hand trying to get me to play with her or watching her lay behind me pulling out hunks of fluff from a new-found inside passage.

Oh, and the crusty look to the fur? Yep, dried dog slobber.

I’d previously posted about how x0xb0x #888 was generating no audio after powerup, and with Roxie now gone I had time to start digging into what was wrong.

I’d already known that the power supply, digital half (sequencer), DAC, and VCO were working fine, so I set to work tracing things back through the schematic from the headphone out. Eventually I found that I was able to see a waveform on the first half of the BA6110, after the op-amp (pins 6 and 7) but before the buffer. I didn’t see anything after the buffer (pin 8).

So, I think I have a bad BA6110, which is one of the rare / hard to find parts in the x0xb0x. This is just what I was afraid of.

Being typically paranoid of my own work I double-checked soldering, checked for shorts, and all the other normal things like that, but I really think the problem is with the buffer.

Last Monday I had Wide Open West CATV and internet service installed. The installer was a nice guy, did just what I wanted, and did a good job putting the new junction box on the outside of the house. As requested he left the Comcast line going into the house, replaced the old splitter, and let me take care of the data side of things (very basic to set up; no Comcastic walled garden crap), and had an MCard for the TiVo.

The only problem I had is that he wasn’t familiar with setting up TiVos and forgot to check for reception of HD channels. A phone call to WOW! service after he left got those turned on and everything was set.

Thus far I’ve been mostly happy with the data service. Tests at DSLReports.com have shown that I can achieve the claimed 15Mbps downstream and 2Mbps upstream quite regularly. Everything has been much faster in real use as well, and uploads to my photo gallery are far, far faster now.

I intend to write up a more technical description of how I like the service, including how I intend to use the three IPs (DHCP assigned) that I’m allocated as part of the service, but that will have to come later. For now I’ve got some other projects to wrap up.

After a bit over a week here it’s time for Roxie to go back home. Danielle arrived here last night right as I returned from Brian’s birthday party, and after some gift returning / shopping stuff she left today with Roxie in the back of the car.
