Bug#856505: No sound in Raspberry Pi 2, missing module?

[eHenry Berg <ehenry.berg@gmail.com>]

Package: linux-image-4.9.0-2-armmp-lpae
Version: 4.9.0-2

My Raspberry Pi 2 does not give any sound from the 3.5 mm jack.

# cat /etc/apt/sources.list
deb http://ftp.fi.debian.org/debian sid main contrib non-free
deb-src http://ftp.fi.debian.org/debian sid main contrib non-free

# ls /proc/asound
    ls: cannot access '/proc/asound': No such file or directory
# modprobe snd-bcm2835
    modprobe: FATAL: Module snd-bcm2835 not found in directory
/lib/modules/4.9.0-2-armmp-lpae

In Rasbian configuration:
https://github.com/raspberrypi/linux/blob/rpi-4.9.y/arch/arm/configs/bcm2709_defconfig
CONFIG_SND_BCM2835=m

In Debian configuration:
/boot/config-4.9.0-2-armmp-lpae
I do not have "CONFIG_SND_BCM2835=m".

I think the sound does not work for me because the module snd-bcm2835
does not exist.
Can you configure kernel version 4.10 to include snd-bcm2835 as a
module, when it comes to sid.
