[BUG] Audio support for MSI Vector GP68HX 13VH with Realtek ALC274

[joenaess]

Hello, the internal speakers are not working on my MSI Vector GP68HX 13VH running Pop!_OS 22.04.

Symptoms

• Audio works correctly via headphones (jack and Bluetooth).
• The system uses the sof-hda-dsp driver for the built-in audio.
• The aplay -l command only lists HDA NVidia HDMI outputs and does not create a device for the internal Realtek card.
• The hdajackretask tool can detect the Realtek ALC274 codec chip, but there is no corresponding ALSA sound card to configure.
• In pavucontrol (PulseAudio Volume Control), a sof-hda-dsp device is visible, and its volume meter moves when audio is played, but no sound is produced from the speakers.

Troubleshooting Steps Taken

• Manually installed the latest sof-bin firmware from the official GitHub releases.
• Verified that alsamixer channels for Speaker and Master are unmuted.
• Attempted to use hdajackretask, but it cannot be used because no ALSA card is created for the Realtek codec.

It appears the kernel driver is failing to properly register the Realtek ALC274 as a usable ALSA card device.

@joenaess can you provide your kernel logs. Adding @shumingfan for guidance on ALC274.

@joenaess Could you share the alsa-info? $ alsa-info

@KailangYang Could you check that and support?

This speaker amp was not own by Realtek. This need supported by AMP vendor.

Moved from FW to kernel as this is a codec driver issue.

@joenaess Unfortunately it looks the amplifier vendor is not supporting this hardware in Linux.

ah, too bad... I like it except for this issue...
