Alguém recebeu um Samson Meteor Mic trabalhando no Linux / ALSA?
Eu tentei pesquisar no Google, mas não encontrei nenhuma menção ao Samson Meteor no Linux.
Kernel / ALSA / Audacity, veja o dispositivo. Infelizmente, não consegui gravar nada. arecord se recusa a trabalhar e o Audacity congela completamente quando pressiono o botão de gravação.
arecord -l me dá:
**** List of CAPTURE Hardware Devices ****
...
card 1: Mic [Samson Meteor Mic], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
arecord -L me dá:
...

Mas, por exemplo arecord -f cd -D default:CARD=Mic retorna apenas mensagens de erro:
ALSA lib pcm_direct.c:1052:(snd1_pcm_direct_initialize_slave) unable to start PCM stream
ALSA lib pcm_dsnoop.c:604:(snd_pcm_dsnoop_open) unable to initialize slave
arecord: main:654: audio open error: Broken pipe
e em dmesg eu acho isso:

Obrigado por qualquer ajuda.
Apenas deixando todos vocês saberem que eu atualizei o kernel recentemente da 2.6.38 para a 3.2.1 e tudo começou a funcionar como um encanto.
Editar: Você tem que ativar CONFIG_USB_EHCI_TT_NEWSCHED no seu kernel para que isso comece a funcionar. Eu tive as mesmas mensagens not enough bandwidth no meu 4.1.15 até que eu habilitei isso.
