Hello today, I've got an Ideapad and after I suspend I cannot get the audio to work when the system resumes.
lspci -v returns the following for the audio section: 00:0e.0 Audio device: Intel Corporation Device 3198 (rev 03) Subsystem: Lenovo Device 3807 Flags: bus master, fast devsel, latency 0, IRQ 25 Memory at a1310000 (64-bit, non-prefetchable) [size=16K] Memory at a1000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_skl In the system log I found the following audio related error message as well: Aug 18 12:34:57 ideapad kernel: [ 51.672003] snd_hda_intel 0000:00:0e.0: azx_get_response timeout, switching to polling mode: last cmd=0x20bf8100 Aug 18 12:34:57 ideapad kernel: [ 52.684197] snd_hda_intel 0000:00:0e.0: No response from codec, disabling MSI: last cmd=0x20bf8100 Aug 18 12:34:57 ideapad kernel: [ 53.695872] snd_hda_intel 0000:00:0e.0: azx_get_response timeout, switching to single_cmd mode: last cmd=0x20bf8100 Aug 18 12:34:57 ideapad kernel: [ 53.696078] azx_single_wait_for_response: 9 callbacks suppressed Aug 18 12:34:57 ideapad kernel: [ 53.981143] snd_hda_codec_hdmi hdaudioC0D2: Unable to sync register 0x2f0d00. -5 Aug 18 12:36:42 ideapad kernel: [ 158.417338] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5 Aug 18 12:36:42 ideapad kernel: [ 158.417498] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5 Aug 18 12:36:42 ideapad pulseaudio[1013]: W: [alsa-sink-ALC269VC Analog] alsa-mixer.c: Failed to set switch of Speaker: Input/output error Aug 18 12:36:42 ideapad pulseaudio[1013]: W: [alsa-sink-ALC269VC Analog] alsa-mixer.c: Failed to set switch of Headphone: Input/output error Aug 18 12:36:53 ideapad kernel: [ 169.533192] azx_single_send_cmd: 299 callbacks suppressed Aug 18 13:45:13 ideapad kernel: [ 4269.876500] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5 Aug 18 13:49:47 ideapad kernel: [ 4543.985442] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5 Are there any suggestions I could try to get this to work correctly after suspend/resume events? Thanks in advance, John
