USB capture card audio stopped working after kernel upgrade

I have a Easycap DC60+ USB A/V capture card that works fine under linux. It stopped working after the linux-3.17.3 upgrade.

dmesg logs:

Re: USB capture card audio stopped working after kernel upgrade

I found this. For your case you need to downgrade and report to V4L Mailing List  <linux-media@vger.kernel.org>

Re: USB capture card audio stopped working after kernel upgrade

I reported it to the mailing list as can be seeing here http://www.mail-archive.com/linux-media … 82811.html to no response as of now.

However, I notice it's also happening with the linux-lts kernel.
Anyone else experiencing this?

Re: USB capture card audio stopped working after kernel upgrade

I think it happens with the kernel 3.18.5 too. However, while vlc doesn't output any sound, youtube in firefox is still ok.
