Hello Leif,

Here is what I can do for the moment today at least.

At 12:57 03/02/22 +0100, you wrote:

I didn't try to run other sound application but it looks you are right, see 
below.

Yes, I agree that ALSA is supposed to save it's settings somewhere.
I have just tried to set 96000 then rebooted but the speed is 48000.
I could even use OSS's 'savemixer' but no joy.
ALSA people forgot to work for sampling rate rather than default 48000 :-)

I think this was caused by the init sequence of alsa during the boot.
I will let alsa not come up in boot sequence and see what happens.
Maybe the result will be tomorrow....

One more thing to remind:

There is "numid=41" options in "amixer" which seems to be the value for 
EEPROM of the card.
numid=41,iface=CARD,name='ICE1712 EEPROM'
  ; type=BYTES,access=r----,values=32
  : 
values=0xd6,0x33,0x14,0x12,0x1d,0x01,0x15,0x80,0x01,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x44,0x03,0x03,0x00,0x00,0x03,0x03,0x00,0x00,0x00,0x00,0x00

I'm afraid it's a bit dangerous command, I don't know.

Good night for now,
