Hi Everyone, I've got a mini PC that after the system resumes from suspend it seems to have some problems with the audio working through HDMI. The audio through the headphone jack continues to work.
If I reboot, the audio begins working through HDMI again. Here's some information: uname -v #1 SMP Debian 4.19.132-1 (2020-07-24) lspci -v | grep -i audio 00:0e.0 Audio device: Intel Corporation Device 3198 (rev 03) sudo dmesg: [10179.980426] azx_single_send_cmd: 72 callbacks suppressed [10180.264169] snd_hda_codec_hdmi hdaudioC0D2: Unable to sync register 0x2f0d00. -5 [10200.307622] azx_single_send_cmd: 341 callbacks suppressed [10200.855109] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2b8000. -5 [10200.855748] snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2b8000. -5 [10267.357734] azx_single_send_cmd: 282 callbacks suppressed [10267.640702] snd_hda_codec_hdmi hdaudioC0D2: Unable to sync register 0x2f0d00. -5 Any suggestions you could help me with in order to get the audio working more reliably? I added the line in /etc/grub.d/40_custom snd_hda_intel.probe_mask=0x01 and updated grub but it hasn't resolved the issue. Any suggestions would be appreciated! Thanks in advance John
