Hi,

I am new to Alsa community..

I am getting ALSA underrun occurred. Not able to get what causing the error. My embedded device runs ON MIPSEL and is 32 bit system.
Application is develop using QT.
While my application running I am getting the error. Just ALSA underrun occurred message displays continuously no other info appears on my console.
Following are the things that developer of our system used..

1. ALSA Driver

File: alsa-lib-1.0.23.tar.bz2

1. Extract package to some folder.

2. Execute: “./configure --host=mipsel-linux --prefix=/opt/alsa/alsa-lib-1.0.23/mipsel --disable-python --disable-aserver”

2. ALSA Utils

File: alsa-utils_1.0.16.orig.tar.gz

1. Extract package to some folder.

2. Execute: “./configure --host=mipsel-linux --prefix=/opt/alsa-utils-1.0.16/build-mipsel --with-alsa-inc-prefix=/usr/include --with-alsa-prefix=/opt/alsa-utils-1.0.16/depends/dep-mipsel/usr/lib --with-curses=ncurses --enable-static=yes”

Please let me know if any other package I need to build and install or more information you need.

I tried runing alsa-info.sh script on my device and following o/p I got.

# /mnt/usb/alsa-info.sh &
# modprobe: invalid option -- c
BusyBox v1.16.1 (2010-04-21 00:19:10 IST) multi-call binary.

Usage: modprobe [-qfwrsv] MODULE [symbol=value]...

Options:
 -q Quiet
 -f Force
 -w Wait for unload
 -r Remove module (stacks) or do autoclean
 -s Report via syslog instead of stderr
 -v Verbose
