[linux-audio-user] xmms-jack 'couldn't open audio' problem

Hi, I have this problem when using xmms-jack output plugin in xmms.. If I run it as a normal user, I get usually "Couldn't open audio..." error box, but when running as root it works without problem. Could this be a permission issue or something? jack-rack, alsaplayer and ams don't have this kind of problem at all. jackd runs in realtime -mode, kernel is 2.6.9-rc2-mm4-VP-S7 xmms 1.2.10, xmms-jack 0.10 (0.9 has same issue, tested it too..) Here is some debugging output: xmms (xmms-jack verbose and trace mode enabled): [...] JACK_GetVolumeForChannel:deviceID(0), returning volume of 25 for channel 0 JACK_GetVolumeForChannel:deviceID(0), returning volume of 25 for channel 1 JACK_OpenEx:bits_per_channel=16 rate=44100, input_channels=2, output_channels=2 JACK_OpenEx:jack_port_name = NULL JACK_ResetFromThis:resetting this->deviceID(0) JACK_OpenEx:bytes_per_output_frame == 4 JACK_OpenEx:bytes_per_input_frame == 4 JACK_OpenDevice:creating jack client and setting up callbacks JACK_OpenDevice:client name 'bio2jack_0_7504' JACK_OpenDevice:setting up jack callbacks JACK_srate:the sample rate is now 48000/sec JACK_OpenDevice:engine sample rate: 48000 JACK_OpenDevice:creating output ports JACK_OpenDevice:port 0 is named 'out_0' JACK_OpenDevice:port 1 is named 'out_1' JACK_bufsize:the maximum buffer size is now 256 frames JACK_bufsize:expanding buffer from this->buffer_size == 0, to 1024 JACK_bufsize:called JACK_OpenDevice:calling jack_activate() ERR: JACK_OpenDevice:cannot activate client JACK_OpenEx:error opening jack device JACK_GetVolumeForChannel:deviceID(0), returning volume of 25 for channel 0 JACK_GetVolumeForChannel:deviceID(0), returning volume of 25 for channel 1 jackd verbose mode: [...] load = 0.3697 max usecs: 13.000, spare = 5320.000 new client: bio2jack_0_7504, id = 3 type 2 @ 0xb6555000 fd = 20 23:07:43.989 Audio connection graph change. registered port bio2jack_0_7504:out_0, offset = 3072 registered port bio2jack_0_7504:out_1, offset = 4096 gave capabilities to process 7504 23:07:44.152 Audio connection change. load = 0.3818 max usecs: 21.000, spare = 5312.000 Any help would be appreciated. :) Thanks. --jussi
