Hey everyone... I'm a bit of a linux newb, so please bear with me. I'm using Ubuntu and attempting to get a Roland UA-100 setup with ALSA. The driver appears to load ok, however aplay will hang when trying to play any wave files (doesn't play any sound, has to be forcibly ended). Attempting to test in the Multimedia Systems Selector results in the 'Failed to construct test pipeline for Alsa' message. qjackctl actually starts Jack ok, but pressing the play button on the transport will not start it (it immediately flashes back to stopped)... Here's the results of aplay -l: card 0: UA100 [UA-100], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 and the results of lsmod | grep snd: snd_usb_audio 68160 3 snd_pcm_oss 46368 0 snd_mixer_oss 16128 2 snd_pcm_oss snd_pcm 78344 3 snd_usb_audio,snd_pcm_oss snd_page_alloc 10120 1 snd_pcm snd_usb_lib 13824 1 snd_usb_audio snd_hwdep 8608 1 snd_usb_audio snd_seq_dummy 3844 0 snd_seq_oss 29440 0 snd_seq_midi 8608 0 snd_rawmidi 22816 2 snd_usb_lib,snd_seq_midi snd_seq_midi_event 6656 2 snd_seq_oss,snd_seq_midi snd_seq 44688 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 21764 2 snd_pcm,snd_seq snd_seq_device 8204 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 48644 13 snd_usb_audio,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_hwdep,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 9184 2 snd usbcore 104316 5 snd_usb_audio,snd_usb_lib,ndiswrapper,uhci_hcd and a cat /proc/asound/cards: 0 [UA100 ]: USB-Audio - UA-100 Roland UA-100 at usb-0000:00:1f.4-2.2, full speed Am I overlooking something simple? TIA for any help getting this thing working!
