No Audio on Rockchip SoC

[sunnystormy]

I just recently installed this OS on my Chromebook, but I've been unable to get any audio. I've got ALSA and PulseAudio installed, but all I get is a barely audible fuzzy noise from speakers and headphones. Does anybody else with a Rockchip-based SoC have this issue?

what is
$this->bbcode_second_pass_code('', ' aplay -l ')
?

[sunnystormy]

aplay -l returns:

$this->bbcode_second_pass_code('', 'card 0: ROCKCHIPI2S [ROCKCHIP-I2S], device 0: Audio HiFi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: RockchipHDMI [RockchipHDMI], device 0: RockchipHDMI dw-hdmi-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
')

I've also run "speaker-test" without any audio coming out.

what is your
$this->bbcode_second_pass_code('', ' .asoundrc ')
?

in my case

$this->bbcode_second_pass_code('', 'aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ODROIDHDMI [ODROID-HDMI], device 0: I2S.27 dit-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
')
$this->bbcode_second_pass_code('', '.asoundrc
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}')

Looks like I don't have one. : /

Do I need to create one, and if I do, where do I put it?

[hatahata50]

in my case

$this->bbcode_second_pass_code('', ' /home/foge/.asoundrc ')

[sunnystormy]

No dice. : (

Setting the card value to either "1" or "0" produces no audible sound.

Also "lsmod" prints out:

$this->bbcode_second_pass_code('', '

')

Unless I'm mistaken... I'm not seeing any audio modules being loaded.

---EDIT---

I looked up the SoC files inside of the Linux Kernel and found out that this brand didn't receive proper audio support until several versions later. Should I just upgrade the kernel?
