sound without jack, no sound with jack

If I use audacity by itself, it can make sounds, on every output possible that it detects. If I use jack (following the tutuorial) I get no sounds, from anything. I am able to see all the programs and they all seem to connect properly, but no actual sound comes out. My driver for jackd is alsa, output device is hw:0 hw:0,0 or USB Midi device. with jackd running audacity shows "JACK Audio Connection kit: alsa_pcm" Using portaudio: v19 with jack unloaded. (killed) audacity shows OSS: /dev/dsp ALSA: HDA NVidia: ALC883 analog (hw:0,0) ALSA: front ALSA: surround40 ALSA: surround51 ALSA: surround71 ALSA: default ALSA: dmix (all Using portaudio: v19) They all work, except for dmix. The same type of thing happens using ZynAddSubFX. It works on it's own, but doesn't work with Jack. Any clues as to what is happening? user@debian:~$ lspci 00:00.0 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a1) 00:01.0 ISA bridge: nVidia Corporation MCP61 LPC Bridge (rev a2) 00:01.1 SMBus: nVidia Corporation MCP61 SMBus (rev a2) 00:01.2 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a2) 00:02.0 USB Controller: nVidia Corporation MCP61 USB Controller (rev a2) 00:02.1 USB Controller: nVidia Corporation MCP61 USB Controller (rev a2) 00:04.0 PCI bridge: nVidia Corporation MCP61 PCI bridge (rev a1) 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2) 00:06.0 IDE interface: nVidia Corporation MCP61 IDE (rev a2) 00:08.0 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2) 00:08.1 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2) 00:09.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0b.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0c.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0d.0 VGA compatible controller: nVidia Corporation Unknown device 03d0 (rev a2) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:06.0 Communication controller: Conexant Unknown device 2f40 01:09.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000 Controller (PHY/Link) 03:00.0 Ethernet controller: Marvell Technology Group Ltd.

If you are using midi. You need to make a link in Jack from the midi device to the sound device. Like Zyn. So open up Jack Audio controller. Go to the connect tab. Now click on the midi tab. You should see your USB midi device. Now lets open up ZynAddFX. Now you should see open on the left side of jack. Now drag from your usb midi on the left side to the right side to Zyn. It should be a green thin line. Now play your midi device and it should trigger Zyn. See if that helps. Gobby

Try it once selecting (default) for both input and output devices, and then selecting HW0 at "Interface"

No, I didn't mean that. I

No, I didn't mean that. I believe the HW0 is the normal onboard sound system. I will try removing the usb midi and see what difference that makes though. (just in case).

Just correct me if I understand you incorrectly. You said that HW0 is a USB Midi device? This might be your problem. USB Midi devices are, as the name clearly states, Midi devices, and as such have no actual audio outputs. The problem normally comes in that these devices, although they have no audio outputs, use a common audio chip as the interface, and the chip *has* audio outputs. So, you are playing your audio to two little pins floating in the wind inside the case of your USB Midi device... What you need to do, is select a audio card that actually has audio outputs. Typically the card that is connected to the speakers you want to use. It may be HW1, or HW2, but the device name normally displayed in "Jack Control" will hint you to the correct interface. If you still have problems, check out the User FAQ section 10, to make sure your HDA NVidia ALC883 is placed at HW0 in jack as well. If you conquered this problem you have passed you linux new(ish)bie initiation and can consider yourself ready to make serious music under the best new audio platform around! Good luck and let us know if this helped. Cheers,
