[Alsa-user] Unreliability from a VX Pocket V1 card

[Alistair Matthews]

Title: Message

Hello All,

 

I've managed (with your help) to get my Digigram VX Pocket V1 card working with ALSA. However it has been a bit unreliable. I can use aplay, xmms and other sound playing apps. But whenever I stop jackd (either by pressing Crtl-C in the console which ran it, or by closing the console window, or by using kill, or even by shutting down the system) the whole system freezes completely and will not respond to anything. Also arecord doesn't seem happy: I tried to use it to record 5 seconds of sound using the --duration=5 switch. But it didn't stop after 5 secs, or at all, and no new sound file is created when I interrupt it.  Another thing is that referring to the id "vxpocket" doesn't work, e.g. running "jackd -d alsa -d vxpocket", despite the fact that it appears in modules.conf as show below. Any ideas?

 

My .asoundrc file is as follows:

pcm.vxpocket {
   type hw
   card 0
}

ctl.vxpocket {
   type hw
   card 0
}

and module.conf is like this:


probeall scsi_hostadapter ide-scsi
alias eth0 via-rhine
probeall usb-interface usb-uhci


# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-vxpocket
# module options should go here
options snd-vxpocket id="vxpocket" enable=1

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
 
above snd-via82xx snd-pcm-oss

The last line was commented out but seemingly appeared again snd-via82xx is used by my other Linux kernel which doesn't have the low latency patch etc.

 

Cheers!
