Dear mailing list individuals,
I currently am using an ASUS STRIX RAID DLX sound card. It contains the following processor: C-Media USB2.0 6632AX High-Definition Sound Processor (Max. 384KHz / 24bit)
More information: https://www.asus.com/Sound-Cards/STRIX-RAID-DLX/specifications
It gets detected as so on Debian testing with Linux kernel 4.6: card 1: DLX [STRIX RAID DLX], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: DLX [STRIX RAID DLX], device 1: USB Audio [USB Audio #1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: DLX [STRIX RAID DLX], device 2: USB Audio [USB Audio #2] Subdevices: 1/1 Subdevice #0: subdevice #0
The output of the card has been wonderfully fine ever since I have had it, but the microphone bit has always been troublesome. On Linux Mint 17.3 it would not work (kernel 4.1 I believe).
On Linux Mint 18 (kernel 4.4) it started working but it is incredibly quiet. On the loudest setting, I have to put the microphone against my mouth for anyone to hear.
On the same system using on-board Intel audio, this issue does not occur. I am using Debian testing to have more recent software, but nothing made a difference.
What can I do about this? I do not really know whether I need to contact the Linux kernel guys or ALSA. I am rather inexperienced with Linux driver things.
Sincerely yours, Desperate Individual
