I don't have pulseaudio installed, perhaps pulseaudio has an additional volume control and you need to increase this, too, by using pavucontrol as suggested by the link you posted? Did you already tested it? Is there a setting regarding +4 dBu / -10 dbV or something related to a possible included microphone amp for MacOS? Does your MacOS use a proprietary driver or like Linux a class compliant default thingy? What is the product name? And what does http://www.cmedia.com.tw/support say to this issue?

Could you please explain about the details of your experience and environment as much as possible, so that we can realize them?

[Alsa-user] Random audio failures during reboot
Hello all, I see random audio playback failures during reboot and the error message is: (snd_pcm_hw_open):(open '/dev/snd/pcmC0D0p' failed (-77)) Has anybody seen these kind of issues? Probably a timing issue in setting up the sound card? Thanks in advance, Linux sound newbie -- ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user

In your case, it's probably "PCH" or "HDMI". Regards, Clemens -- ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
[Alsa-user] Microphone volume on USB soundcard very low, are there any snd_usb_audio options?
Hello all, I have a problem with the microphones volume being way too low (compared to what the same connector does under macOS) on a USB "soundcard". I have described the whole ordeal here (with pictures and system info): http://unix.stackexchange.com/questions/299322/microphone-volume-on-usb-soundcard-very-low-snd-usb-audio-options tl:dr: A "dedicated microphone adapter", eg. a C-Media USB soundcard device with an XLR mic connector (Bus 001 Device 004: ID 0d8c:0008 C-Media Electronics, Inc.) that uses snd_usb_audio yields a very low mic input even when fully turned "up" all the way under alsamixer. There's no "boost" control for the input device. The same adapter yields a clean and strong signal under a different OS. As always, thanks for any pointers, any help or encouraging words ;) Best, Christian. -- ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
