Sox hangs when trying to access dsp device

sajko · 2006-04-18 08:15:59

Hello, i have a problem with my TerraTec Cinergy 400TV Mobile (Pcmcia) and my HDA Intel sound card, im not entirely sure which is the problem.

I start out with loading the snd_hda_intel module for the sound card and that works fine, /dev/dsp is created and i can stream sound with xmms without any problems.

i then load saa7134 module for my Cinergy card, with options:
card=47 tuner=12 oss=1
and then i also load saa7134-alsa and that creates the other dsp device /dev/dsp1

so far so good, the sound still works fine. I start tvtime and i see video feeds, but no sound, this is where sox comes in, i need to stream the audio from dsp1 (which is the sound capture device on the Cinergy card) and tunnel it to dsp (hda intel device)

To start sox i use the following line:
/usr/bin/sox -t ossdsp -w -c2 -r 32000 /dev/sound/dsp1 -t ossdsp /dev/sound/dsp

When i do this sox freezes without giving me any return errors.

anyone ever had this problem? if not i can post a strace of what it does.

okey i figured some more out, i did a strace on sox when it ran (this was my own compiled version) and when it came to opening the dsp1 device it just hangs with
open("/dev/dsp1

it doesnt even finish the line

full print out of strace:
