The HT-Omega eClaro is a PCI sound card built on the C-Media CMI8788 (Oxygen HD) controller, with PCI subsystem ID 7284:9783. Output hardware: - AK4396VF stereo DAC: front L/R output, connected via SPI CE0 - CS4362A 6-channel DAC: surround, center/LFE, and side outputs, connected via SPI CE1 with a 3-byte [0x30, reg, val] frame The CS4362A uses inverse attenuation encoding (0 = 0 dB, 127 = max attenuation) and a 0.5 dB/step logarithmic scale. Volume TLV is set to TLV_DB_SCALE(-6350, 50, 0) to match the hardware. The channel-to- register mapping was verified by listening test: - Pair 1 (regs 7/8): side L/R (ALSA channels 6/7) - Pair 2 (regs 10/11): center/LFE (ALSA channels 4/5) - Pair 3 (regs 13/14): rear L/R (ALSA channels 2/3) Input hardware: - CS5361 stereo ADC: Line In and Mic In capture GPIO assignments: - GPIO 0 (0x0001): CS4362A RESET# (active-low, driven high) - GPIO 2/3: CS5361 M0/M1 (sample rate mode) - GPIO 5 (0x0020): front output stage enable (driven high) - GPIO 8 (0x0100): headphone amplifier enable Signed-off-by: Ferus Castor <feruscastor@proton.me> Assisted-by: Claude:claude-sonnet-4-6 Link: https://patch.msgid.link/20260601015848.128566-1-feruscastor@proton.me Signed-off-by: Takashi Iwai <tiwai@suse.de>
