alsa-project/alsa-ucm-conf pull request #403 was opened from pulak1901: Hi, I've been trying to get sound working on this tablet. Since I'm quite new to alsa UCM & PA/PW, I took a look at the existing sc7180-rt5682-max98357a config as well as the [ChromeOS UCM for this system](https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/refs/heads/main/overlay-strongbad/chromeos-base/chromeos-bsp-strongbad/files/coachz/audio/ucm-config/sc7180-adau7002-max98357a/HiFi.conf). It looks like the hardware does not have any hw controls (`alsamixer -c 0` shows no bars), so it was easy to get internal speakers & microphone working (albeit without any gain for the mic). However, I could not get the USB HDMI/DP output to work seamlessly. Even though I've mentioned the JackControl, PA tries to open the device, errors out, and fails to find a working profile. It only works if I reboot the system with HDMI plugged in. Jack detection itself seems to be fine(from the output of `amixer -c 0 contents`), so is there something else I should be doing here? <details><summary>amixer -c 0 contents</summary> <p> ``` numid=1,iface=CARD,name='HDMI Jack' ; type=BOOLEAN,access=r-------,values=1 : values=off numid=5,iface=PCM,name='ELD',device=2 ; type=BYTES,access=r--v----,values=128 : values=0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00 numid=4,iface=PCM,name='IEC958 Playback Default',device=2 ; type=IEC958,access=rw------,values=1 : values=[AES0=0x04 AES1=0x00 AES2=0x00 AES3=0x01] numid=3,iface=PCM,name='IEC958 Playback Mask',device=2 ; type=IEC958,access=r-------,values=1 : values=[AES0=0xff AES1=0xff AES2=0xff AES3=0xff] numid=2,iface=PCM,name='Playback Channel Map',device=2 ; type=INTEGER,access=r----R--,values=8,min=0,max=36,step=0 : values=0,0,0,0,0,0,0,0 | container | chmap-fixed=FL,FR ``` </p> </details> <details><summary>pulseaudio -vvv</summary> <p> ``` ...
