in the beginning, there was the Sharprom...it's music player was quite good, the sound was crisp and loud...but there was little bass response. and since it doesn't have an equalizer the problem could not be fixed. Then there was the PdaXrom which gave us Xmms... well, im here to discuss about the crappy sounds emanating from my (quality)headphones driven by Xmms. as i said the sound is crappy, apparently unbalanced and there is no way of fixing that since xmms equalizer doesnt work on our Z's. fine, i said to myself...just install some other player that has a working equalizer. So i hit the forums...And end up being seriously dissapointed....

apparently there is no music player with an acceptable working equ AFAIK.
Which is kind of strange 'cos it seems that our Z's sound chips(wolfson WM8750) have basic equ capabilities which can be seen on this link:

http://staging.wolfsonmicro.com/products/WM8750/

I also remember reading somewhere that our Z's have the same DAC as ipod's do, can anyone confirm/negate that?

So what's the problem? is it so hard to make a software interface to existing hardware dsp capabilities? And why doesn't xmms equ work?

eviLjazz :-
This has to be the best thing since.. I got my Zaurus!
Thank you for you work. biggrin.gif

Running Cacko 1.2.3 and the sharp ported music player.

Some feed back I use the Sharp CEH-2 remote I've noticed the following:-

If I have the mixer open and set to headphones the remote won't work in my music player no matter where the focus or even if the mixer is open.
Although if I set the mixer to auto detect everything works 100% remote changes songs stops the player ect..
Not sure if thatís what it should to do that but I though you should know.

Two other things :-
1) I needed to reboot with the CEH-2 in for it to work ( needs more testing to confirm and its not just me been dumb )
2) My Planex CW-CF11x stoped working. I canít get it to pick up won't load the firmware, this did work fine before I upgraded with no modifications canít even scan for wifi.

Don't mean to sound picky! I really need work out how you are compiling the kernels for this. Do it my self! Help out a bit! tongue.gif

Thanks for you effort!

Yeah, I think I know what the problem is. Thanks for reporting! I'll see if I can fix it over the weekend. Finishing Quasar has higher priority though. At least I've got the remocon so I can do the debugging here.

Hrmm, okay. Do you know which driver was used with the old kernel? hostap?

Sure, no problem!
For a start grab the current sources here:
http://www.katastrophos.net/zaurus/kernels....20-v55.tar.bz2
You can also just grab a snapshot from my SVN repository: https://svn.katastrophos.net/zaurus-kernel-2.4.20/trunk

The README file included in the archive has instructions on how to build the kernel yourself. This should be sufficient if you roughly know how to build a kernel for your desktop system. It also shows how to setup the cross compiler. PM me if you need help.
