frailn Posted September 10, 2008 Author Report Share Posted September 10, 2008 Where are my chips???! All your chips are belong to Wilba.Seriously, it's interesting that packages are delivered from the USA faster to Germany than to the UK. Wonder why that is?

frailn Posted September 10, 2008 Author Report Share Posted September 10, 2008 So I havnt received my chips yet either. Im in US so I figured I would get them early on. Just making sure nothing odd happened with my package?You should have received yours by now, since the other US orders were delivered. Let's give it one more week to make sure it's not a USPS-being-slow issue. Let me know at the end of next week if they have not arrived.

frailn Posted September 13, 2008 Author Report Share Posted September 13, 2008 To everyone that participated in this bulk order - I have some potentially bad news. Lemonhorse, who has been designing the AY-3-8912 board recently contacted me regarding the sound chips for this bulk order. Here is what he had to say:Hi frailn,I think there is a big problem: now that i've checked the AY 3 8912A/P - 9151 CCA chips in depth I detect that none of my 4 chips are able to add NOISE to Tone A, B or C. My first check was quick and dirty I just checked the Tone A B and C and the Envelope.I think You should now that first.I Don't know - if it matters:my 2 reference chips are named:GI - AY 3 8912 8311 CDAthe new chips are named:microchip - AY38912A/P 9151 CCAI'm sorry for that bad news.I'm not sure if this means all the chips we ordered have this issue. But, I think it is only fair to let you know what Lemonhorse discovered this week when testing the four chips I shipped to him.Here are my next steps:1. I'm doing some research to find out if this problem has been documented on any other website or forum. I don't know if the mixing issue is by design or a flaw. I would like to find out.2. If I don't find any info in step one, or if I discover that it is not a design issue, I'm going to send my two chips to Lemonhorse to test. 3. Depending upon the results listed above, I may ask my seller for refund. However, this may be difficult since the chips have been spread to the four corners of the earth.My guess at this point is that we have a version of the chip that doesn't mix noise with the tones. Maybe this new-old-stock was designed for a particular company and they were trying to save money by cutting back on features? All just a guess, really. I'll keep you updated as I progress in my research.If you have any input, questions or assistance along these lines, please speak up!

nILS Posted September 13, 2008 Report Share Posted September 13, 2008 [ x ] Shit happens.My 2 cents: Don't worry about refunds too much, if you manage to find out what the problem is (design change, revision problems, ...) that's all that I'd be interested in ;-) Quote Link to comment Share on other sites More sharing options...
frailn Posted September 13, 2008 Author Report Share Posted September 13, 2008 Thanks, nILS...I spent an hour this morning running google searches on different variations of AY 3 8912/noise/mixer/tone/issues/etc... without any luck. The schematics and information I have found always lump the 8910/8912/8913 together when outlining information regarding the way tone/mixer/noise work together. There is no information I can find regarding the differences between manufacturing runs.Since the noise/tone mixer is controlled by internal workings of the chip, and since all four of the chips I sent to Lemonhorse have the same issue, I'm inclined to think the problem is related to a particular manufacturing run.For now, I'm open to suggestions on figuring out the source of the issue. I may be limiting myself on figuring this out due to a lack of experience. Quote Link to comment Share on other sites More sharing options...

polpat Posted September 13, 2008 Report Share Posted September 13, 2008 Just received my 5 chips just yesterday! Thank you!Looking for info on different chip manufacturers version...The joke:I guess probably Microchip made this "noiseless" version for Dolby industry... ;D Quote Link to comment Share on other sites More sharing options...
frailn Posted September 13, 2008 Author Report Share Posted September 13, 2008 Lemonhorse - can you post sound samples comparing noise-mix vs non-noise-mix? Quote Link to comment Share on other sites More sharing options...
lemonhorse Posted September 13, 2008 Report Share Posted September 13, 2008 Lemonhorse: Can you rule out software problems?All functions are working except the noise. So It's not a general Core AY chip data-communication problem I guess.I double checked the issue with my 2 reference AY 3 8912 chips (GI - AY 3 8912 8311 CDA). Maybe I overlook something.Any ideas?

lemonhorse Posted September 13, 2008 Report Share Posted September 13, 2008 uufff - I'm new to all that jack and ardour2 stuff. the recording quality is still lousy.but anyhow... ;) Chip Tune Test Sequence: Just Tone A and NOISE Tone Aay38912GI1.wav.mp3 == my reference chipay38912microchip0.wav.mp3ay38912GI1.wav.mp3 Quote Link to comment Share on other sites More sharing options...
frailn Posted September 13, 2008 Author Report Share Posted September 13, 2008 Thanks, for posting the sounds! Well, I guess it's not a project killer, but it sucks not to be able to get the full potential from the chip. Quote Link to comment Share on other sites More sharing options...
lief138 Posted October 14, 2008 Report Share Posted October 14, 2008 FrailnWell if you are not in too much of a rush things work out. My 2 chips came today. What a long wait but you notice how no one freaked out or anything. I think my package was in the same box as wilba's package ;)OK thanks for the chips dude.Lief Quote Link to comment Share on other sites More sharing options...
mrcam Posted October 14, 2008 Report Share Posted October 14, 2008 Some no-news about the noise problem. Microchip tech service was unable to find a reference datasheet for their version of the ay-3-8912 chips. And in other way, Sergey Bulba ( http://bulba.untergrund.net ) never met that problem... he gave me the email of another guy but i still did not contact him however.I have the soundchips in a shoe box but not enough time for now to build the synth :-\ Quote Link to comment Share on other sites More sharing options...
nILS Posted October 14, 2008 Report Share Posted October 14, 2008 I've tried *everything* with the chip - no noise. So whatever the other guys did - this specific chip we have does NOT make noise. Quote Link to comment Share on other sites More sharing options...
