Post subject: | DVB-S card with SAA7146 (TechnoTrend TT Budget S-1500 PCI) |
Hi, I find a solution for my old satellite PCI DVB-S card with chipset SAA7146 on a system with LinHES 8.2 plus updates (mythtv 0.27.4-3, LinHES-system 8.2-5). (My dual port DVB-S2 card " Micronas Semiconductor Holding AG nGene PCI-Express Multimedia Controller (rev 01)" have no problem with standard installation of LinHES 8.2) The problem is, that this card is not showing as a DVB-S satellite card, the following error message: dmesg |grep -i dvb Code: Linux video capture interface: v2.00 cx88/2: cx2388x dvb driver version 0.0.9 loaded cx88/2: registering cx8802 driver, type: dvb access: shared To fix this you must edit the file /etc/modprobe.d/alsa-base.conf and put a "#" in the line "options cx88_alsa index=-2" and reboot your system. Code: # Prevent abnormal drivers from grabbing index 0 options bt87x index=-2 #options cx88_alsa index=-2 options saa7134-alsa index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 options snd-usb-audio index=-2 options snd-usb-usx2y index=-2 options snd-usb-caiaq index=-2 Regards Lutz This is for information only: ********************************************************************************************** I have a old "TechnoTrend TT Budget S-1500 PCI" DVB-S satellite card.
