I just installed archlinux on the Chromebook 2. In mate-volume-control under hardware it only lists "Built-in Audio" "Analog mono output". This only works when I select "Headphones" as the output connector, and only in the left channel. Actually, if I select Speakers, it still comes through the headphones at a greatly reduced volume.
I suspect this is not the correct driver. I find these two alsa-lib 1.1.9 files.
pacmd says there is only one card, and it is mono. So how do I get or set up a better sound driver for my Chromebook 2?
$this->bbcode_second_pass_code('', '1 card(s) available.
index: 0
name: <alsa_card.platform-sound>
driver: <module-alsa-card.c>
owner module: 6
properties:
alsa.card = "0"
alsa.card_name = "Peach-Pi-I2S-MAX98091"
alsa.long_card_name = "Peach-Pi-I2S-MAX98091"
alsa.driver_name = "snd_soc_snow"
device.bus_path = "platform-sound"
sysfs.path = "/devices/platform/sound/sound/card0"
device.form_factor = "internal"
device.string = "0"
device.description = "Built-in Audio"
module-udev-detect.discovered = "1"
device.icon_name = "audio-card"
profiles:
input:analog-mono: Analog Mono Input (priority 7, available: unknown)
output:analog-mono: Analog Mono Output (priority 700, available: unknown)
off: Off (priority 0, available: unknown)
')
There are two configuration files that seem to indicate this should be stereo:
$this->bbcode_second_pass_code('', '
/usr/share/alsa/ucm/DAISY-I2S
DAISY-I2S.conf
HiFi.conf
')
