Comment 2 for bug 1201739

I also have a now sound problem with an NVidia card. Here's where I am....

1) PulseAudio is disabled. (Not shown in ps ax, and volume control reports it cannot connect to the server)

2) Moved KDE settings away from alsa device hw:2.7

3) mplayer will use alsa device hw:2.7 and plays just fine.

4) if I start jackd on alsa hw:2.7 while mplayer is using it, jackd reports device is in use.

5) If I start jackd without mplayer running, jackd starts just fine and mplayer then reports the device is in use.

6) jackd creates a system playback sink.

7) Now, with 'mplayer -ao jack x.mp3' jack creates a mplayer source and maps it to the system sink.

8) No sound. Alsamixer reports no applications are playing audio.

9) if I run qjackrec, jackd will map the mplayer source to both the system and qjackreq sinks. qjackreq captures the audio into a .wav file just fine, but still no audio output. After jackd is shutdown, mplayer will play qjackrec's .wav file (via alsa, again on hw:2.7).

10) All the while jackd is running, including the period mplayer is playing into jack, alsamixer reports that no applications are playing sound.

I'm stumped. Alsa works, the alsa device works, jackd works, jackld takes ownership of the propoer alsa device... and nothing.
