Hello,

today I updated kernel to 3.5.4 and noticed, that all my sound from Fast
Track Pro USB Sound Card got mute. I haven't noticed any error reports
or messages, all seems to work, the card is just silent. I downgraded to
3.5.3 and applied patched from usb sound module one by one and found
out, that 3.5.4 minus " ALSA: snd-usb: fix calls to next_packet_size "
works fine:

Does this change require some update of configuration I missed?

There are some informations about device from lsusb:

My system runs 64 bit Arch Linux, there is config used by it:
https://projects.archlinux.org/svntogit/packages.git/plain/trunk/config.x86_64?h=packages/linux&id=59ae346478ff01f0d2dc47b04a3a1297046b1900

How can I proceed with this issue? Any more information I can provide to
help in solving this?

Thank you,
Andrzej Giniewicz.

This was fixed by "ALSA: snd-usb: fix next_packet_size calls for pause case": http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=8dce30c89113e314d29d3b8f362aadff8087fccb

Thank you, now I (and lots of other people) can hear sound again!
Andrzej.
