out crackels on SigmaTel C-major

[Jonas Eriksson]

hey all,

first: thank you for a wonderful driver (I seem to remember a commercial project trying to do this without ever quite succeding... can't remeber what is was called).

one problem though: on my dell laptop, an inspiron 8600 with Sigmatel C-major, I cannot seem to get rid of the crackles.

this is what I've tried:

1. read the earlier posts regrding SigmaTel
2. force 16-bit
3. different buffersizes
4. disable input
4. different versions of asio4all (the 2.2 as well as a4a23pre.exe and A4Av23p2.exe)

...but the crackles are still there (less when I raise the buffer size but quite audiable).

I'll now download some new wdm-driver for my SigmaTel but does anyone have any ideas on other things to try?

again: thank you Michael!

regards,
- Jonas

almost forgot: I'm using Nuendo 2.2 and my dell is equipped with a centrino 1.6 mhz.

(the volume is much higher using asio4all compared to the standard asio multimedia - is this normal?)

[Jonas Eriksson again]

hey all.

problem solved! (or perhaps more accuratley: work-around found

it seems that my crappy Sigmatel likes 48 khz much better than 44 khz. changed samplerate in my project and voila! everything works just fine.

This exactly is what the "Always resample..." option is for. It circumvents the WDM driver's poor attempts at resampling so you may still be able to run your projects at 44.1kHz if you enable this option.

hey Michael,

I actually tried that but it doesn't work on my setup. - the crackles are still there if I try to play 44 khz sounds.

but I'm just glad it works on 48 kHz - what difference could 4 khz make anyway

happy new year! regards,
