hi all,

I'm trying to get alsa work with kernel 2.6.18.1 on PXA270 platform, 
after rebuild kernel with CONFIG_SND_PXA2XX_AC97 enabled and boot, 
device is found. then I build alsa-lib and alsa-utils, and run aplay to 
play a wav file, but get the following error:

# aplay Front_Center.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 
48000 Hz, Mono
aplay: set_params:1005: unable to install sw params:
start_mode: DATA
xrun_mode: STOP
tstamp_mode: NONE
period_step: 1
sleep_min: 0
avail_min: 0
xfer_align: 10
silence_threshold: 0
silence_size: 0
boundary: 1434451968

What does this error mean? Can anybody help?

Thanks,

Damwid

This is probably to do with this ARM gcc bug:-

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27363

and this is now fixed in gcc. :)

Fwiw, Open Embedded (http://www.openembedded.org/) builds an ARM EABI
toolset without this bug. It can also cross compile alsa-lib and all the
audio utilities for you as well.
