Surprisingly, this could also be reproduced on APL/Electro simply by adding "drm.debug=14 log_buf_len=1M". On my device this is 100% reproducible. So lets no say its GLK-RVP Specific bug. Add APL also in bug description. Case 2.[NO HDA Verb Timeout, as there no Codec #%d probe error; disabling it...\n", c); happened here] Interestingly, I one time just added simple printk(3 lines additions) in skl.c and I could see this issue to, but less rate of reproduction. In this case I saw: [ 11.548286] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Port [ 11.548298] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: CPU DAI System Pin not registered [ 11.557716] chintan: skl_i915_init err:0 [ 11.560182] chintan: skl_probe_work err: 0 [ 11.566803] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Port [ 11.566816] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: CPU DAI System Pin not registered [ 11.567440] snd_soc_skl 0000:00:0e.0: codec #2 probed OK [ 11.580011] HDMI HDA Codec ehdaudio0D2: Max dais supported: 3 [ 11.580021] HDMI HDA Codec ehdaudio0D2: codec register ehdaudio0D2 [ 11.580030] HDMI HDA Codec ehdaudio0D2: ASoC: dai register ehdaudio0D2 #3 [ 11.580032] HDMI HDA Codec ehdaudio0D2: ASoC: dynamically register DAI ehdaudio0D2 [ 11.580035] HDMI HDA Codec ehdaudio0D2: ASoC: Registered DAI 'intel-hdmi-hifi1' [ 11.580037] HDMI HDA Codec ehdaudio0D2: ASoC: dynamically register DAI ehdaudio0D2 [ 11.580040] HDMI HDA Codec ehdaudio0D2: ASoC: Registered DAI 'intel-hdmi-hifi2' [ 11.580042] HDMI HDA Codec ehdaudio0D2: ASoC: dynamically register DAI ehdaudio0D2 [ 11.580045] HDMI HDA Codec ehdaudio0D2: ASoC: Registered DAI 'intel-hdmi-hifi3' [ 11.580048] HDMI HDA Codec ehdaudio0D2: ASoC: Registered codec 'ehdaudio0D2' [ 11.580184] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Port [ 11.580192] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: CPU DAI System Pin not registered [ 11.580303] chintan: probe_codec probe_codec_ret: 0 Case 3 [NO HDA Verb Timeout, as there is no Codec #%d probe error; disabling it...\n", c); happened here]: Below case also shows no sound card: [ 4799.781611] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Port [ 4799.781640] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Capture Port [ 4799.781651] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio Reference cap [ 4799.781661] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt Audio DMIC cap [ 4799.781671] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt HDMI Port1 [ 4799.781682] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt HDMI Port2 [ 4799.781692] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding Bxt HDMI Port3 [ 4799.781702] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding SSP5-Codec [ 4799.781712] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding SSP1-Codec [ 4799.781722] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding dmic01 [ 4799.781731] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: binding iDisp1 [ 4799.781740] bxt_da7219_max98357a_i2s bxt_da7219_max98357a_i2s: ASoC: CODEC DAI intel-hdmi-hifi1 not registered As you can also see whenever there is no sound card it also always shows ASoC DAI registration error : ASoC: CODEC DAI intel-hdmi-hifi1 not registered OR ASoC: CPU DAI System Pin not registered At this point I feel we should also explore more area and not just HDA Verb responses.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
