Bug Description

Binary package hint: linux-image

I have a KWorld ATSC 115 TV Tuner card that stops working when coming back from sleep/suspend. The way to make it work again is to unload and reload the kernel modules:

sudo rmmod saa7134_dvb
sudo rmmod saa7134_alsa
sudo rmmod saa7134
sudo modprobe saa7134

I have a similar issue with a Compro DVB-T300[1]. The device works fine after a cold boot, but not after a restart. I haven't tried it after sleep/suspend.

For me, adding the following line to alsa-base.conf worked:

options saa7134 card=70

The "card=70" setting is a device-specific workaround. The official list is at [2], and seems to suggest that the the KWorld ATSC 115 should have "card=90" instead of "card=70". My card isn't on the official list - I got card=70 from [3].

I've attached my details to bug #374184, which is an unrelated bug I'm having with the same TV card.

The original reporter might have some luck with adding a line "options saa7134 card=90" to his /etc/modprobe.d/alsa-base.conf, but I'd rather he not blame me if it melts his computer.
