<br clear="all">Hi,<br><br>since I installed Fedora 12, I realized that I have no more an "Analog Loopback" available<br>in alsa, which allowed me to route the capture sources on my sound card back in as PCM audio.<br>
<br>I tried upgrading alsa-driver to 1.0.22, but nothing changed. The only option I have now<br>is using arecord and aplay to simulate the loopback. Although this scheme woks fine,<br>arecord / aplay just die from time to time (kind of randomly), with no apparent reason.<br>
This is the command I use:<br><br>arecord -D hw:0,0,0 -d 0 -f S16_LE -c2 -r128000 | aplay -f S16_LE -c2 -r128000 -D default &<br><br>Another question is how to use amixer to control the volume of an application in a way<br>
that allowed me change the volume of any sound card installed on my system. Since I<br>must specify the card using "-c 0", for instance, if I switch the sound to another card using pulseaudio,<br>I can no longer control the volume of this new card. Unfortunately, there is no "-c default" in amixer ... <br>
<br>amixer -q -c 0 set PCM 80%<br><br>Would there be a better way of doing that?<br><br>Thanks.<br><br>-- <br>Paulo Roma Cavalcanti<br>LCG - UFRJ<br>
