Update the kernel to 4.4,but no sound

Postby yafengabc » Mon Apr 18, 2016 2:50 am

the modules snd_bcm2835 is loaded
$this->bbcode_second_pass_code('', '
snd_bcm2835 26904 0
snd_pcm 87158 1 snd_bcm2835
snd_timer 21995 1 snd_pcm
snd 62729 3 snd_bcm2835,snd_timer,snd_pcm
')
but in /dev/snd only two devices
$this->bbcode_second_pass_code('', '
[yafeng@RaspArch ~]$ find /dev |grep snd
/dev/snd
/dev/snd/timer
/dev/snd/seq
')
can't open alsamixer:
$this->bbcode_second_pass_code('', '
[yafeng@RaspArch ~]$ LANG=C alsamixer
cannot open mixer: No such file or directory
[yafeng@RaspArch ~]$ LANG=C sudo alsamixer
cannot open mixer: No such file or directory
')

and not any info in dmesg:
$this->bbcode_second_pass_code('', '
[yafeng@RaspArch ~]$ LANG=C dmesg |grep snd
[yafeng@RaspArch ~]$
')

thanks for all
