time to lower the DAC volume, I discovered its possible to blow up the speaker :)
<peterm6881>
We've gone from an amp less than 1 Watt, to an amp at 2.5 Watts, but the speaker is still the same 1 Watt speaker. Can you drop the volume on the Master DAC output from 100% to 41%. It wont let me set it to 40%
<peterm6881>
dont change the version tag
<peterm6881>
cheers
<Xogium>
oww dang that's not nice
<Xogium>
blowing the speaker part, that is
<Xogium>
but yeah, I knew it could be done. Driving the amp too high for what the speaker can handle will most probably do that to any speaker
<Xogium>
shouldn't it be the line out volume we lower ?
<Xogium>
I actually never touched the DAC volume ever, my unit only set the line out volume
<Xogium>
and unmute DAC
<peterm6881>
well, you would only lower the line output if the source had become distorted due to overloading
<peterm6881>
which it isnt
<peterm6881>
think about it, what you want is a nice fat signal coming in, to keep it above the noise floor
<peterm6881>
and then adjust the master volume to get the level you want, nice and clean
<Xogium>
but then, what the hell blew up the speaker ?
<peterm6881>
we upgraded the amplifier
<Xogium>
why did it never blow up before ?
<peterm6881>
read back
<Xogium>
I mean on my speedsaver it was that big fat amp, and my line out and DAC were both to 100%
<peterm6881>
We've gone from an amp less than 1 Watt, to an amp at 2.5 Watts, but the speaker is still the same 1 Watt speaker.
<Xogium>
I'm kinda confused
<peterm6881>
lol thats why yours frightened the horses in Belgium
<Xogium>
I understand why it blew up but… if that's so, why did mine never blow up
<peterm6881>
your never had either of the 1 Watt speakers we've used since I sent those
<Xogium>
huh… really ?
<peterm6881>
we've used two different 1 Watt speakers, one is mounted in the case, the other is PCB mounted on the HAT
<Xogium>
hmm
<Xogium>
but what's mine then ?
<peterm6881>
yours has an ABS-230-RC, its rated at 4 Watts
<Xogium>
oh
<Xogium>
that explains it then
<peterm6881>
i originally wanted really badass audio, for alternative use cases
<Xogium>
and boy is it loud with that 2.5w amp
<peterm6881>
but eh speaker is too expensive and too hard to mount
<peterm6881>
the *
<peterm6881>
the amp you have is an OEP3W module
<Xogium>
hmm. Maybe this speaker would work on my player for the blind
<peterm6881>
which uses the same 2.5 Watt amplifier we care currently using in the latest HATS. They initially didnt work, no audio output, but they are repaired now
<peterm6881>
are *, not care
<Xogium>
yeah I remember that. It's great you could fix it at home
<peterm6881>
so, basically, the 2.5 Watt amp is able to fry the 1 Watt speaker. I thought it would be ok, given it only beeps occasionally
<Xogium>
I guess not
<peterm6881>
I knew it was likely we would need to drop the volume. Its desirable anyway, it will get rid of most of the crackles and hiss
<peterm6881>
Ive done some testing and 41 on the DAC is the sweet spot
<peterm6881>
it'll save me dropping them all through alsamixer and alsactl store
<peterm6881>
have you had a good day?
<Xogium>
hmm can't say good or bad, just plain ordinary day
<peterm6881>
i havent even had dinner yet
<peterm6881>
the lights are very bright on the Odyssey, i wish I hadnt bought a see through case :)
<peterm6881>
gonna have to tape them up :)
<peterm6881>
thanks for your help yesterday
<Xogium>
oh did you get that tty stuff working ?
<peterm6881>
its working perfectly on the sd card now
<peterm6881>
yes, its getting the account to autologin
<peterm6881>
i havent set up a playlist or anything, just commencting and uncommenting lines in ~/.profile same as before
<peterm6881>
commenting
<Xogium>
ah, good
<peterm6881>
i noticed i couldnt ssh into it, i dont think its using port 22
<Xogium>
hmmm no, it has no ssh installed by default
<Xogium>
that's why
<peterm6881>
ahh now you mention it, i think i saw that on the wiki
<peterm6881>
i'll have to set that up
<peterm6881>
any progress on the image for the nand?
