Package: pulseaudio
Version: 14.99.2+dfsg1-1
Followup-For: Bug #991337
Dear Maintainer,
I can confirm the same segfault behaviour when plugging in Digidesign MBox 2 USB soundcard. Pulseaudio crashes immediately as the soundcard is initialized, as shown in the dmesg loglines:
[105992.407921] usb 2-2: New USB device found, idVendor=0dba, idProduct=3000, bcdDevice= 1.43
[105992.407924] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[105992.407926] usb 2-2: Product: Mbox 2
[105992.407927] usb 2-2: Manufacturer: Digidesign
[105996.008564] usb 2-2: Digidesign Mbox 2: 24bit 48kHz
[105996.846468] pulseaudio[29671]: segfault at fffffffffffffff8 ip 00007f95f844d0d7 sp 00007ffc82ff4370 error 5 in libasound.so.2.0.0[7f95f843f000+8d000]
When the USB soundcard is not plugged in, pulseaudio works as expected. This has also been the case before those errors started to occur (can't pinpoint exact date, haven't been using the sound card much recently)
