Hello! I have a BT878-family 4-input a/v capture card. It was in service and working great a couple of years ago, before I put it on the shelf for a while, and now I'm taking it out of retirement for some light CCTV work. Video capture (v4l2) from the the card works great, and my four other ALSA devices are all working great -- but on the audio side of the BT card, I get zero ALSA devices. The bttv module detects the card as: [ 1062.768422] bttv: 0: detected: Provideo PV150A-1 [card=98], PCI subsystem ID is aa00:1460 [ 1062.768423] bttv: 0: using: ProVideo PV150 [card=98,autodetected] [ 1062.779217] bttv: 1: detected: Provideo PV150A-2 [card=98], PCI subsystem ID is aa01:1461 [ 1062.779219] bttv: 1: using: ProVideo PV150 [card=98,autodetected] [ 1062.790159] bttv: 2: detected: Provideo PV150A-3 [card=98], PCI subsystem ID is aa02:1462 [ 1062.790160] bttv: 2: using: ProVideo PV150 [card=98,autodetected] [ 1062.801118] bttv: 3: detected: Provideo PV150A-4 [card=98], PCI subsystem ID is aa03:1463 [ 1062.801119] bttv: 3: using: ProVideo PV150 [card=98,autodetected] The snd-bt87x module loads successfully, but nothing for it shows up in "arecord -l" and /proc/asound/cards. I'm loading snd-bt87x with the module parameters "index=4 id=bttv load_all=1". The snd-bt87x reports nothing to dmesg or syslog (that I can identify), but modprobe succeeds, and lsmod shows that it is loaded. I'm attaching the output of "aadebug" in case it's helpful. I'm not sure what could be escaping me -- help! Thanks, Eric |
