Hi Mark, Sorry again. You suggest to create a new structure for these entries, for example: /* Out Bypass mixer switch */ static const struct snd_kcontrol_new max98088_out_bypass_mixer_controls[] = { SOC_DAPM_SINGLE("INA Switch", M98088_REG_4A_CFG_BYPASS, 7, 1, 0), SOC_DAPM_SINGLE("MIC2 Switch", M98088_REG_4A_CFG_BYPASS, 4, 1, 0), SOC_DAPM_SINGLE("REC Switch", M98088_REG_4A_CFG_BYPASS, 1, 1, 0), SOC_DAPM_SINGLE("SPK Switch", M98088_REG_4A_CFG_BYPASS, 0, 1, 0), }; Let me know. Thanks in advance. Tommaso

Hi, I added this reg as regular controls because this reg is pretty generic as you can see this controll bypass of some output, not all. What do you think about? Thanks, Tommaso

That sounds exactly like a DAPM control, please make them DAPM controls.

Hi Mark, Perfect, thanks for your suggestion. I'll do it in V2. Tommaso

Hi Mark, Sorry again, but I'm quite new on alsa subsystem. I need an help on figuring out on how to implements your solution. From what you suggest I got that I need to create a bypass mixer for every switch (4 -> SPK, REC, MIC2, INA): /* Out Mixer SPK */ static const struct snd_kcontrol_new max98088_output_bypass_spk_mixer_controls[] = { SOC_DAPM_SINGLE("SPK Bypass Switch", M98088_REG_4A_CFG_BYPASS, 0, 1, 0), }; /* Out Mixer REC */ static const struct snd_kcontrol_new max98088_output_bypass_rec_mixer_controls[] = { SOC_DAPM_SINGLE("REC Bypass Switch", M98088_REG_4A_CFG_BYPASS, 1, 1, 0), }; /* Out Mixer MIC */ static const struct snd_kcontrol_new max98088_output_bypass_mic_mixer_controls[] = { SOC_DAPM_SINGLE("MIC2 Bypass Switch", M98088_REG_4A_CFG_BYPASS, 4, 1, 0), }; /* Out Mixer INA */ static const struct snd_kcontrol_new max98088_output_bypass_ina_mixer_controls[] = { SOC_DAPM_SINGLE("INA Bypass Switch", M98088_REG_4A_CFG_BYPASS, 7, 1, 0), }; After that, I need to route the new control mixers on the switch: {"Out Mixer SPK", "SPK Bypass Switch", "RECN"}, {"Out Mixer REC", "REC Bypass Switch", "RECP"}, {"Out Mixer MIC", "MIC2 Bypass Switch", "MIC1"}, {"Out Mixer INA", "INA Bypass Switch", "INA"}, Then route the bypass switch to the new output: {"SPKL", NULL, "SPK Bypass Switch"}, {"RECN", NULL, "REC Bypass Switch"}, {"MIC2", NULL, "MIC2 Bypass Switch"}, {"MIC1", NULL, "INA Bypass Switch"}, I'm in the right way? What do you think about? Can you point me a similar bypass switch into the kernel to take as reference? Thanks in advance Regards, Tommmaso

From what you suggest I got that I need to create > a bypass mixer for every switch (4 -> SPK, REC, MIC2, INA): It depends how the audio is routed - that would be a fairly unusual structure for hardware but it's possible.

What do you think about? That's pretty much it if they're a bunch of separate things. > Can you point me a similar bypass switch into the kernel to take as reference? If you search for "Bypass" in sound/soc/codecs you'll see a bunch of examples - a lot of the Wolfson devices have bypass paths for example. You'll see that for example with wm9713 the bypass paths go into mixers that have other inputs rather than being totally separate things - I see that this device has things like "Right SPK Mixer" which look like they might fit here.
