On a machine I did a "zypper dup" to update from 15.2 to 15.3, the 15.3 does not have sound at bootup. Sound card is: # lspci | grep -i audio 16:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller The 15.2 works fine. 15.2: #dmesg | grep -i audio [ 0.502138] ACPI: Added _OSI(Linux-Lenovo-NV-HDMI-Audio) [ 9.892740] snd_hda_codec_realtek hdaudioC0D0: ALC1150: SKU not ready 0x00000000 [ 9.894094] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC1150: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:line [ 9.894980] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 9.895870] snd_hda_codec_realtek hdaudioC0D0: hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) [ 9.896760] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ 9.897662] snd_hda_codec_realtek hdaudioC0D0: dig-out=0x1e/0x0 [ 9.897662] snd_hda_codec_realtek hdaudioC0D0: inputs: [ 9.897663] snd_hda_codec_realtek hdaudioC0D0: Front Mic=0x19 [ 9.897664] snd_hda_codec_realtek hdaudioC0D0: Rear Mic=0x18 [ 9.897664] snd_hda_codec_realtek hdaudioC0D0: Line=0x1a [ 9.912613] input: HD-Audio Generic Front Mic as /devices/pci0000:00/0000:00:08.1/0000:16:00.4/sound/card0/input4 [ 9.913543] input: HD-Audio Generic Rear Mic as /devices/pci0000:00/0000:00:08.1/0000:16:00.4/sound/card0/input5 [ 9.914476] input: HD-Audio Generic Line as /devices/pci0000:00/0000:00:08.1/0000:16:00.4/sound/card0/input6 [ 9.915416] input: HD-Audio Generic Line Out as /devices/pci0000:00/0000:00:08.1/0000:16:00.4/sound/card0/input7 [ 9.916344] input: HD-Audio Generic Front Headphone as /devices/pci0000:00/0000:00:08.1/0000:16:00.4/sound/card0/input8 On 15.3: #dmesg | grep -i audio [ 0.132048] ACPI: Added _OSI(Linux-Lenovo-NV-HDMI-Audio) [ 5.112574] hdaudio hdaudioC0D0: Unable to bind the codec Yet when I go into Yast and reconfigure the card, the sound works until a reboot happens. What am I missing? Mark
