This happens for me too if the last profile I manually selected on the sound card was a surround profile (however, I get sound from the speakers unlike you, but the kernel driver might auto-mute the speaker output in your case). The code that is responsible for automatically switching between headphones and speakers doesn't work correctly during startup if the selected profile is not the analog stereo profile. So, what profile is initially active when this happens? If it's not the stereo profile, then it's probably the same issue that I observe here. You can check the profile with command   LANG=C pactl list cards | grep "Active Profile" -- Tanu
