| Post subject: | R5F1 and Analog Cable on the pcHDTV HD-5500 |
OK, so I bought myself one of these new fangled mythtv boxes all the kids are talking about and I've got pretty much everything working. The box I'm using is a Dragon v2.0 with Dual pcHDTV HD-5500s. The only remaining obstacle is sound on analog cable. Video works just fine, but audio is not happening. When I enable the cx88-alsa stuff the two analog devices show up fine. But once I configure the analog options for DVB in mythtv-setup to use those devices, I get an error message when I try to watch analog cable and it's "no go" until I switch the setup back. So, has anyone got this stuff working and is ready to give me the quick fix that will forever put me in their debt? |

Getting analog sound working on KnoppMyth R5F1 with a pcHDTV HD-5500 cx88-alsa.diff cx88-tvaudio.diff Recompiling modules with patches: 1. Download kernel source from ftp://knoppmyth.net/R5/linux-source-2.6 ... om_all.deb 2. Install package and bunzip archive located in /usr/src/. 3. Apply the attached attached diffs to the following files: /usr/src/linux-source-2.6.18-chw-13.tar/linux-source-2.6.18-chw-13/drivers/media/video/cx88/cx88-alsa.c /usr/src/linux-source-2.6.18-chw-13.tar/linux-source-2.6.18-chw-13/drivers/media/video/cx88/cx88-tvaudio.c 4. Cd to /lib/modules and move 2.6.18-chw-13 to 2.6.18-chw-13.old 5. Cd to usr/src/linux-source-2.6.18-chw-13 and run "make menuconfig". 6. Scroll down and select "load an alternate configuration file". 7. Specify the file "/boot/config-2.6.18-chw-13", save and exit. 8. Run "make modules", then "make modules_install". 9. Run "depmod" and reboot. Tweaks: 1. Add the following line to /etc/modprobe.d/alsa-base: options cx88-alsa index=-2,-2 2. Add the following line to /etc/modprobe.d/dvb-core: options dvb_core dvb_shutdown_timeout=0 3. Run mythtv-setup, in the Recorder Options of your DVB card, check "Open DVB card on demand". 4. Enter frontend setup, modify the recording profile for Software Encoders. Set Live TV's sampling rate to 48000. |
