Installing the sound card
Yes, it is supported by Linux, using the driver snd=hdspm
After putting the sound card in the PCIe slot, you can switch on the computer and SPBLinux should recognize it. To confirm, you can use the following command
cat /proc/asound/cards 0 [default ]: HDSPAES32 - HDSPM MADI RME HDSPM AES32 at 0xe5300000, irq 5 cat /proc/asound/card0/hdspm RME HDSPM AES32 (Card #1) Rev.e9 IRQ: 5 Registers bus: 0xe5300000 VM: 0xd0820000 --- System --- IRQ Pending: Audio=0, MIDI0=0, MIDI1=0, IRQcount=15809 HW pointer: id = 0, rawptr = 0 (0->32704) estimated= 0 (bytes) MIDI FIFO: Out1=0x0, Out2=0x0, In1=0x0, In2=0x0 Register: ctrl1=0x10102dc, status1=0x10000, status2=0x80, timecode=0x3 --- Settings --- Size (Latency): 4096 samples (2 periods of 16384 bytes) Line out: on , Precise Pointer: off ClearTrackMarker off, Emphasis off, Dolby off Sample Clock Source: Autosync System Clock Mode: Slave Preferred Sync Reference: Word System Clock Frequency: 192000 Double speed: Single wire Quad speed: Single wire --- Status: Word: Sync Frequency: 192000 AES1: Sync Frequency: 192000 AES2: Sync Frequency: 192000 AES3: Sync Frequency: 192000 AES4: Sync Frequency: 192000 AES5: No Lock Frequency: 0 AES6: No Lock Frequency: 0 AES7: No Lock Frequency: 0 AES8: No Lock Frequency: 0 AutoSync ref = Word
If you get the above lines, or something similar, then your sound card is installed properly.
Setting up configuration file
The configuration file is placed under the folder named /brutefir/start/hdspaes. To know more about this configuration settings, you can display all the settings using the command
amixer contents
To display to current setting, run the script first than ^C to stop. Type
amixer > /test
Then look for the information under the main directly under /test
One thing to note is that in the pass, the max value for RME sound card is 32768. If you set it at 65535, you are actually adding gain to the incoming signal and you can have the problem of clipping.
To make things simpler, I will attach the contents here
