<Guest54638> do you have noise from you NN spk or headphones?
<Guest54638> background noise, hiss,fissile that's noticeable when listening to music?
<Guest54638> I find it more noticeable when using ear pieces than big headphones

<Web-aptosid876_> do you hear background noise when listening to music?
<Web-aptosid876_> on the nano note?
<Web-aptosid876_> I'm desperate to know, if my NN is damaged or it's a design fault.
<wpwrak> not sure if a lot of people are a) using the ben to listen to music AND b) are around
<wpwrak> you may have better luck posting to the qi-hw mailing list

<DocScrutinizer05> I wouldn't be surprised to find it's either a design flaw or a production defect where a filter/buffer capacitor got soldered in a defunct way
<DocScrutinizer05> if it was the latter, it's at least easy to fix
<DocScrutinizer05> sorry, I never seen a NN, so I can't help

<Web-aptosid876_> I believe I have ask on the mailing list before and didn't get a response, or maybe i didn't, I forget. but thanks
<Web-aptosid876_> the noise is a fizz which goes up and down a bit. any hints on how to find out if that is the case?
<Web-aptosid876_> ....if it is the case of replacing a capacitor
<Web-aptosid876_> but I can try again on the mailing list...
<DocScrutinizer05> might be interference between two clocks mixing their noise on VDD
<DocScrutinizer05> VDD-analog should be properly filtered
<DocScrutinizer05> as mentioned I have no NN and no schematics at hand
<DocScrutinizer05> adding a huge plus small low ESR RF enabled buffer capacitor directly to the VDD-ana and VSS-ana-GND pins will for sure not hurt

<Web-aptosid876_> thanks
<Web-aptosid876_> http://downloads.qi-hardware.com/hardware schematics soomewhere here?
<DocScrutinizer05> Q6 WTF?!
<DocScrutinizer05> but well, that's only built-in amp+speaker
<DocScrutinizer05> anyway weiiiiiird
<DocScrutinizer05> SW1 maxes so much sense ;-P
<DocScrutinizer05> makes*
<DocScrutinizer05> could use NN as a hearing aid without any CPU load X-P
<DocScrutinizer05> or - without headphone plugged in - even for a nice acoustic theremin (http://en.wikipedia.org/wiki/Theremin), I guess
<Web-aptosid876_> I had a opps on disabling the mic-to-spk bypass. opps. I had the levels maxed and got dreadful feedback. could that have damaged it?
* whitequark recalls an early Chromebook whose speakers literally caught fire if you ran a stock ALSA on it

<Web-aptosid876_> interesting whitequark
<Web-aptosid876_> so might it be worth me getting a new NN? (I'll hope to find a good use for the old one, so don't worry. or maybe sell it if some needs it)
<whitequark> nah, unlikely that you have damaged it
<Web-aptosid876_> my one was 2rd hand in the first place.
<whitequark> and even if you did, it should be relatively easy to fix
<Web-aptosid876_> well I did fry the charging IC. had to replace it :D
<Web-aptosid876_> bloody surface mount ic's hehe :D
<whitequark> a minute with a hot air gun and you're done
<Web-aptosid876_> I was experimenting with alternative power supplys and opps
<Web-aptosid876_> don't have a hot air gun.
<Web-aptosid876_> I guess there is hacker spaces
<Web-aptosid876_> but yea, I'll happily fix it if possible :D
<whitequark> a hot air gun is cheaper than a new NN ;)
<whitequark> especially if you buy it off craigslist
<Web-aptosid876_> well I guess there is that
<Web-aptosid876_> here's some recording noise recs I did last year: http://george.the-petries.co.uk/nanonote/rec/audiointerfer/

<wpwrak> DocScrutinizer51: what is SW1 ? do you mean S1, "RESETK" ?
<DocScrutinizer51> NN audio "SW1" A/D/A bypass
<DocScrutinizer51> mic -> amp
<wpwrak> something in the SoC ? or an actual component ? i dno't see any switch there on page 6 of Lb60_schematic (except the one built into J3)
<wpwrak> neither on page 2, for that matter

<wpwrak> aah, inside the chip. that explains it. thanks !
<wpwrak> aha, the first goal
<wpwrak> judging by the noise level, it must have been by river ...
<wpwrak> ... yep,
<wpwrak> oh, no. that was before. in silence. now it was for boca, 1:1. interesting.

<wpwrak> aha, another one. very noisy. 2:1 for boca ?
<wpwrak> naw, river. damn, i'm getting the noise levels in my area wrong
<wpwrak> (the two are the principal clubs in buenos aires, so it's a major event every time they meet)
