(In reply to erasmocaponio from comment #30) Based on your current analysis, this internal speaker is using an external amplifier and is likely to be cs35l41 hda mounted on i2c. You can try commenting on patch 31.
By the way, I would like to ask how to read SSDT. I saw that you said that after decompiling from this file, you read - Device (SPK1), _HID "CSC3551", _UID 0, I2C address 0x36 - Device (SPK2), _HID "CSC3551", _UID 1, I2C address 0x37 To be honest, I don't know how to handle this file. Is there any tutorial or documentation for me to learn? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1982483 Title: No sound from built-in speakers HP Pavilion All-in-One Desktop 27-ca1xxx (ALC274) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1982483/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
