[linux-audio-user] HDSP and "play"

[linux-audio-user@xxxxxxxxxxxxxxxxxx (linux-audio-user@xxxxxxxxxxxxxxxxxx)]

Hi,

Matt again.  So if you remember I have this problem where my hdsp freezes any time I use play (or any app that utilizes the play program, like maybe (?) audacity...).  When I use play, it plays the soundfile, but afterward, I can't open any programs that would use my soundcard (some open but say it can't find the device or that the device is in use).  When I run "ps aux" there's no indication of play being there.  However, when I run play and it gets to the end of the soundfile, I hear what sounds like an amp clip, and I get this:

/usr/bin/play: line 205:  1686 Segmentation fault      sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects


The 1686 before the Segmentation fault seems to change depending on the soundfile (1802 is another I've had)... I'm not really sure what that number is.  So I opened up my /usr/bin/play in vi to see what was in line 205 (I've displayed the last bit of the program):

# If name is "rec" then record else assume user is wanting to play
# a sound file.
if [ "$program_name" = "rec" ]; then

    # Don't send data to stdout if they are reading from it.
    if [ "$filename" = "-" ]; then
      echo "Send break (control-c) to end recording" 1>&2
    else
      echo "Send break (control-c) to end recording"
    fi
    sox $volume $arch_defines $fopts $device $fopts2 "$filename" $effects 

else
    sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects
fi

Line 205 is the final fi, but the line above that is the one that appears in the "error" message I get running play.  Is there something in that line (or the rest of the program) that I should change to get it to work with my hdsp?  I have an onboard nVidia soundcard that works with play just fine, and aplay works fine with both cards.  Is it a problem in the play program, or maybe the alsa hdsp driver I'm using?  Another thing I noticed is that when I use play, the signal is being sent to all the channels on the hdspmixer, whereas when I use aplay, it sends it just to the first two.  What gives?

Also, when this happens, I've been rebooting the machine... is there a way maybe to restart alsa instead?

Thanks,

Matt
