Hello dear all,
It's possible de increase CONFIG_SND_MAX_CARDS to 256 and increse sample
rate to 384khz.
Actualy i build my own kernel as:
sed -i 's/SNDRV_PCM_RATE_CONTINUOUS |
SNDRV_PCM_RATE_8000_192000,/SNDRV_PCM_RATE_CONTINUOUS,/g'
./sound/drivers/aloop.c
sed -i 's/192000/768000/g' ./sound/drivers/aloop.c
grep -rnl './' -e "CONFIG_SND_MAX_CARDS=32" | xargs -i@ sed -i
's/CONFIG_SND_MAX_CARDS=32/CONFIG_SND_MAX_CARDS=256/g' @
search and replace 32 by 256 in and
./debian.master/config/annotations:CONFIG_SND_MAX_CARDS
and for alsa utils:
git clone git://git.alsa-project.org/alsa-lib.git alsa-lib
./gitcompile --with-max-cards=256
make install
git clone git://git.alsa-project.org/alsa-utils.git alsa-utils
./gitcompile --with-max-cards=256
make install
Thanks in advance.
