Do you get no recognition at all? Or just poor recognition?
If poor recognition, have you tried creating a dummy user and seeing if you can train up that new user? If the spectral characteristics of the input are different under ALSA -- yeah, they shouldn't be, but clearly it happens -- then you might need to retrain to get any accuracy.
If you have no recognition whatsoever, I suspect an issue with configuring ViaVoice to recognize the micorophone input. First, I'd try "arecord" to see if I can use *any* program to capture speech. I have found that I can't get any recordings working on my machine (Via 8235, Asus A7V8X) unless I use a battery-powered microphone.
"arecord -l" (lower-case L) should give you legit recording inputs.
I personally find that "esd" doesn't work with ALSA 0.9.4, and I kill esd servers that are running. I use OSS or ALSA directly, through their respective modules (for xmms, for example) or through the /dev/dsp input if the program I'm using only has OSS.
If esd if off, I'll hazard a guess there's a problem with ViaVoice. I am guessing that you've configured ViaVoice to use /dev/dsp. The only other thing that comes to mind is that ViaVoice may require 8 kHz or 11 kHz PCM input, and with ALSA you can sometimes manage to create 44 kHz or 48 kHz inputs. You might need to fiddle with the default configuration of your inputs, using asound.state, to feed ViaVoice the correct 16 bit, 8 or 11 kHz that it probably requires.

Dear ALSA developers,
Ok, I fixed the previous problem; now running the latest kernel + latest modules (and alsa 0.9.4).
The REAL problem I have is the following:
Recording has always been extremely hard to impossible with linux - one of the applications that I REALLY cannot get working is the speech recognition tool of IBM: ViaVoice.
I downloaded the commercial sound drivers from Front4 and with that it works perfectly. In the past I've also got this to work with the OSS/Free stuff.
However... with ALSA, it has never has worked; and I've tried a lot of things :(.
I can't see this anymore being anything else but a bug in ALSA. The problem however is to find WHY it doesn't work (and then fix it).
I'd like to get some guidance with that.
My setup is as follows:
1) It works (recording speech with microphone) when using the Front4 commercial sound drivers. 2) With ALSA, playback works and I hear myself back over the speakers when I talk into the microphone. I even can let it 'sing around' by capturing Mic (of course) and turning on max. "AC97" and "Capture == Igain". Also "AC97 Capture" was set to the maximum. In fact, I turned EVERYTHING on to the maximum with alsamixer, unmuted everything and captured Mic [1]... No recording.
I am willing to get to the bottom of this, but I am out of ideas right now :/
Please help.
