7 ALSA chips created after rpi-update

My rpi starter kit was supplied with Debian 6.

Yesterday I did the sudo apt-get update and the sudo apt-get upgrade.

Today I installed rpi-update and ran it.

On re-booting I noticed the following listed
[info] Loading kernel module snd_bcm2835.
[ 37.454333] bcm2835 ALSA card created!
[ 37.480195] bcm2835 ALSA chip created!
[ 37.497239] bcm2835 ALSA chip created!
[ 37.512324] bcm2835 ALSA chip created!
[ 37.527232] bcm2835 ALSA chip created!
[ 37.541944] bcm2835 ALSA chip created!
[ 37.556669] bcm2835 ALSA chip created!
[ 37.571246] bcm2835 ALSA chip created!

Is is right to have 7 ALSA chips created?

I did the updating and upgrading in the hope that the 512M memory would be recognised, but my rpi is still using just 256M. Is this right?

Not sure on the chips will have to look at that I think Dom posted this about the memspilt I added it all together and it worked on my wheezy install:

Code: Select all

From the console on the Pi choose one of the 4 options below

sudo wget https://github.com/raspberrypi/firmware/raw/master/boot/arm256_start.elf -O /boot/start.elf

sudo wget https://github.com/raspberrypi/firmware/raw/master/boot/arm384_start.elf -O /boot/start.elf

sudo wget https://github.com/raspberrypi/firmware/raw/master/boot/arm448_start.elf -O /boot/start.elf

sudo wget https://github.com/raspberrypi/firmware/raw/master/boot/arm496_start.elf -O /boot/start.elf

Then reboot:

sudo shutdown -r now

I remember seeing something similar on mine. Each type of sound had its own entry. So a system sound had one, and audio (music) had another and so on.

Current firmware implementation requires that you pick the correct (for you) startXXX.elf and copy it to start.elf on the boot partition.

I've also noticed the repeated ALSA messages - in my case I get 8! :)

Code: Select all

This is a Raspbian Wheezy installation, 512MB, running 496/16 split. Does it with a 256MB device too. Only occurs after an apt-get upgrade, not with the stock 2012-09-18 image.

Edit - now I see this reply:

Ah OK, so it's normal... that's fine then!

Yes. It allows you to do:
aplay file.wav &
aplay file.wav &
aplay file.wav &
aplay file.wav &
aplay file.wav &
aplay file.wav &
aplay file.wav &
aplay file.wav &

(not sure anyone wants to do that, but it's there)

Hello,

This alsa problem happened before, about a month ago. A solution was published in one of the forums.
It was caused by a faulty update file and was corrected by going back to a previous version and
updating again. The correction was published in one of the forums.
Perhaps a new solution will be published.

Regards
