Submitter : Andrzej Giniewicz <gginiu@gmail.com> Date : Thu, 20 Sep 2012 18:33:33 +0200 Message-ID : <505B455D.2040603@gmail.com> References : https://lkml.org/lkml/2012/9/20/346 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: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commitdiff;h=ca150f7ade5973c3bce19261bca6174d5c3cc342 Does this change require some update of configuration I missed? There are some informations about device from lsusb: http://pastie.org/private/odiuw0ve3iszdat9mwpa 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.
