Re: [linrad] FW: Anyone success in ALSA driver for Delta 44?
Thanks for the information.
What I have found/learned so far using man and available mixers :
// taken out from 'man amixer'
amixer [-c card] [cmd]
Shows a complete list of simple mixer controls.
Shows a complete list of simple mixer controls with their contents.
Shows a complete list of card controls.
Shows a complete list of card controls with their contents.
I tried as below (assume Delta 44 card 1 and SB PCI 128 card 0);
# amixer -c 1 cset numid=42 12 <-- this sets to 96000 from default 48000}
numid=42,iface=MIXER,name='Multi Track Internal Clock'
; Item #0 '8000'
; Item #1 '9600'
; Item #2 '11025'
; Item #3 '12000'
; Item #4 '16000'
; Item #5 '22050'
; Item #6 '24000'
; Item #7 '32000'
; Item #8 '44100'
; Item #9 '48000'
; Item #10 '64000'
; Item #11 '88200'
; Item #12 '96000'
; Item #13 'IEC958 Input'
# amixer -c 1 cset numid=43 on <-- this sets rate locked (default off, not
numid=43,iface=MIXER,name='Multi Track Rate Locking'
Above seems rate set 96000 and rate locked ON.
However Linrad doesn't detect the max input speed of 96000Hz.
Only 48000Hz 4 channel 16 bit on "U" command.

I would really be interested in Dominic's solution.
Please encourage him to input here.

You wrote in other post too;

So, should I wait for the release?
