This is the kernel output when the sound is working normally: [ 13.717726] HDA Intel 0000:00:07.0: power state changed by ACPI to D0 [ 13.717737] HDA Intel 0000:00:07.0: PCI INT A -> Link[LAZA] -> GSI 21 (level, low) -> IRQ 21 [ 13.717794] HDA Intel 0000:00:07.0: setting latency timer to 64 [ 13.875499] hda_codec: num_steps = 0 for NID=0x27 (ctl = Surround Playback Volume) [ 13.875743] hda_codec: num_steps = 0 for NID=0x26 (ctl = Center Playback Volume) [ 13.876036] hda_codec: num_steps = 0 for NID=0x18 (ctl = Side Playback Volume) [ 13.876622] hda_codec: num_steps = 0 for NID=0x14 (ctl = Capture Volume)
Sometimes I need to reboot (one or several times) to get this.
