i am trying to change my poweron.snd to a custom boot sound but so far have been unsuccessful. i have:

took a soundbite that is Stereo,44100Hz and 5 seconds long. I'm not sure of the real limit. Exported with audacity
Set Save as type: to "Other uncompressed files"
Clicked Options
set Header to "RAW header-less
and Encoding to Signed 16 bit PCM
click OK and saved as poweron.snd

i also tried just renaming a .wave file to .snd but so far no go anybody know what type of file to use or how to make a custom PowerOn.snd file that will work with the tu :thinking:
 
windows shows it as a au file and au files are bigendian and most windows .wav files are littleendian. so i don't know if that's it or not gonna try converting my .wav to bigendian an see if that works i couldn't find any thing that even would play the default poweron file. although audacity would play it if i imported it as raw but it didn't sound right at all

edit: been reading and i don't think this is the problem. still seems like the first file i tried should have worked ?????????

EDIT: got my first file to play by amplifying it i can now hear it play clearly i may need to tweak the speed a little but it there an working..so the file needs to be a RAW header-less Signed 16 bit PCM (i also had to amplify to 10 db ) saved as poweron.snd see first post on how to save with audacity :)

Well, what Slayer's saying is that the first file will work, but only if it looks exactly like this: poweron.snd

From your original post, it looks like you have it saved as: PowerOn.snd

Linux and Linux-based systems (like Android) ARE CASE-SENSITIVE, even on filenames. So while you have the original sound file as poweron.snd, and the one you made as PowerOn.snd, it's always going to choose the default, because it has the correct name.

I just kinda skimmed this cause I'm short on time but don't save your file as poweron.snd.. save it as poweron.wav and rename it to poweron.snd

i have determined that with audacity it will work both ways saving as a RAW header-less Signed 16 bit PCM "poweron.snd".. or "poweron.wav" then renaming to .snd after you move to sd card. if you rename in windows you get ( "poweron.snd .wav" ) my first file did work the first time but i didn't know it. cause my kid was watching tv. and it was loud enough that i couldn't hear the file playing. later that day i tried it again and heard it playing at a very low volume. so i boosted it 10db in audacity. and now it works fine i don't know if you would have to boost the gain on every sound bite but i had to for the file i was using. (no matter if i saved as .snd or .wav) maybe i will try making another one later and see if it plays ok without the 10db boost might just have been the file i used..

ahh ok, fyi your pc is renaming it to poweron.snd.wav cause it isnt set to show you file extensions so any change you make to an extension is just becoming part of the name before the extension.

yha sometimes it changes the file ext. and sometimes not i will have to change PC to show file ext ...i had forgot i could do that i just got this PC i am working on now. also i did create another poweron.snd file from a new source file an it also needed to be amplified to hear it good.

foot note to naming files with audacity: if you don't specify a file extension when saving. it will export it as raw data. you must specify a file extension. not just a file name. no mater what save options you have chosen. And on that note if you specify .snd windows see's it as a au file and if you chose .wav it of course see's it as a wave file. the default poweron file is seen by windows also as a au file. so that's why i chose to save as poweron.snd not just rename a wave file although both will work..
