Hi all ,
I am using the Hoontech DSP24 with DSP C-Port 2000 for music production. This is similar to Midiman L1010 card , which has the same chipset (ice1712) and a fairly similar card architecture/implementation. So if you are an owner of ice1712 chipset, please do not skip this email :)
Personally, I've been using the external 1U c-port 2000 (based on the ICE1712) for the past 10+ years in linux and i'm very satisfied with it :)
So far I had not bothered with capture/playback from the pci card (DSP24, based on SigmaTel STAC97xx as I read in this link http://www.st-audio.de/products/dsp24.html). I would like to do that now. Of course I want to use these playback/capture ports from within jack
$ cat /proc/asound/cards
0 [DMX6Fire ]: ICE1712 - TerraTec DMX6Fire
TerraTec DMX6Fire at 0xec00, irq 16
1 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9ff8000 irq 45
2 [DSP24 ]: ICE1712 - Hoontech SoundTrack Audio DSP24
Hoontech SoundTrack Audio DSP24 at 0xe400, irq 17
3 [DSP24_1 ]: ICE1712 - Hoontech SoundTrack Audio DSP24
Hoontech SoundTrack Audio DSP24 at 0xd880, irq 18
where for card2:
$ cat /proc/asound/pcm02-00: ICE1712 multi : ICE1712 multi : playback 1 : capture 102-01: ICE1712 consumer : ICE1712 consumer : playback 1 : capture 102-02: ICE1712 consumer (DS) : ICE1712 consumer (DS) : playback 6
I start up jack with master card the #2 as:
$ pasuspender -- jackd -S -dalsa -dhw:DSP24,0 -r44100 -p64 -n2
not sure if this is correct, but I get to see all the channels I expect at least (which is weird because here I see that device 2:0 apparently has only 1p and 1c port ?!?!?!? Can someone explain?)
To do that I tried using zita-a2j and zita-j2a. the commands are the following :
#playbackzita-j2a -d hw:DSP24,1 -c 2 -j DSP24old_out -r44100 -p1024 -n2
#capture
zita-a2j -d hw:DSP24,1 -c 2 -j DSP24old_in -r44100 -p1024 -n2
I am not sure if device hw:2,1 is correct here either. If someone could explain to me the differences of "ICE1712 multi" , "ICE1712 consumer" , "ICE1712 consumer(DS)", I would appreciate it!
right so, I can start the playback port fine - the zita-j2a outputs in cli "Starting synchronisation" every second or so, but it seems to have started up at least.
However I do not get any sound from the line out jack of the pci card. I checked the levels in alsamixer, "PCM" and "Master" are at 100% and not muted. What can I not hear anything?
The capture port is non existent for some reason.
$ Can't open ALSA capture device 'hw:DSP24,1'.
How can I check if a capture port exists for this card? or how can I verify it is not used by someone else (f.e. pulseaudio server, etc) ?
Thank you in advance for your help!
