Sound Quality On R198
« on: October 16, 2007, 04:12:28 pm »
I am trying to use the pdaXrom r198 release for listening to music, but I find it extremely crappy. I hear buzz as if the bass spectrum was overamplified. And it is not because of the headphones. Those are innocent in this...

Is it only my experience, or is it a general problem? I did not find anything serious on forum... Is there any way to improve it?

there's a 2.4 kernel with wm8750 drivers compiled in. check the following thread.

we all know that sound support in the 2.6 kernel has a long way to catch up to the quality of the 2.4 kernel...

Alright. So it seems to be a known issue and it is not just about my (possibly crappy, or lame) setup. From what you say, I understand that the fixing is under way, right? Is there anything I can do in the meantime? Like e.g. installing an alternative driver or so...

Thanks for comments.

Thanks for the info. So it seems Debian is not alone having the sound problem. But OpenBSD can play music well with mplayer (but i haven't tried it).

*coughs* I suggest you guys actually take the correct driver from 2.6 then. As it was written by the company that designed the sound system. Exposes all the power of the codec. And has far supierior sound quality to the 2.4 driver.

http://opensource.wolfsonmicro.com if you need the link to the correct driver.

Nice! A 100% non-guru question: How could I find out the "correct driver" for sound in C1000/3000/3100/3200?

OE selects the right one automagically when building and has appropriate state files for it.

That's all nice. If only mplayer would install on Angstrom smoothly :-(. What is a good driver worth if you cannot play music using it?

Which raises the question-- has anyone actually got this driver running on a 2.6 based (Zaurus) system that plays audio?
..and other than the vaderish "power of the codec" bit, isn't the 2.4 driver (the new one that includes the wolfson stuff) from the same people for the same hardware? Wouldn't they sound the same (assuming both were working)?

Well it works for me on c3200 and c860 devices.

2.4 driver should sound the same as long as it sets the hardware up correctly. Wolfson don't support 2.4 kernel so we were only working on 2.6 in my time there.

All I can figure is people are pulling random bits from here and there and not really understanding what they are doing. If your going to borrow stuff from OE then if you borrow everything stuff should just work. At least for basic sound playback. It is certainly working on Angstrom build from 3pm today on a C3200 device.

So you actually have a working EQ and 3d sound (with manual control --sliders or something- of sound settings)on both an 860 and a 3200 using Angstrom(2.6), and you can play back audio on it?  And this is from simply buidling and installing?

Yes, on the C3200, I havent tested C860 recently

You have to use alsamixer for the complex stuff, but it works. Out of the box the 3200 running angstrom will play audio from speaker. If you plug in headphones it will switch to headphones. I am doing this as I write this :-)
