Re: DVB-T tuner loses lock when starting omxplayer

I can now confirm the RPi works with IT9135, latest kernel & firmware on Arch Linux.

Re: DVB-T tuner loses lock when starting omxplayer

Well, I've solved it partially - it turned out the aerial cable was damaged and attenuated the RF signal. After cutting it short, the tuner stopped losing lock. And by "partially" I mean no thorough tests were made - I am no longer using my Pi to watch TV. Conclusion: make sure the reception is good...

Re: NTFS External HDD - Read Only File System

If you plan to dedicate the drive for Pi (and discard its use with Windows), forget about NTFS. Use ext4 instead - you'll have better performance with it. If you insist on using NTFS (which I don't recommend) with write support, you have to use FUSE and NTFS-3G. sudo apt-get install fuse ntfs-3g Aft...

Re: Building a new kernel

I'm not sure what are you asking for... If you ask for a kernel source, there is a package for that, but AFAIK it is outdated, so you should download the kernel from repository. There are two versions - 3.2.27 (not to be confused with 3.2.27+), and 3.6.y (3.6.11). After you download the kernel, you ...

Re: tvheadend PCTV 340e

We have to clarify two matters: Your tuner is terrestrial (DVB-T), not cable (DVB-C). These two differ a little, in modulation. You cannot use DVB-T on cable networks. The analog part is managed differently than DVB. According to the linuxtv ( http://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_Hybr...

Re: tvheadend PCTV 340e

Something on the way went wrong, because previously dvb-usb-dib0700-1.20.fw loaded without problems. Why this file is no longer in your /lib/firmware directory? Make sure you have two firmware files on your RPi.

Re: Is there a way to connect 2.5 IDE or SATA internally?

More sensible approach is to use USB <--> (S)ATA adapter. You can buy these for a few bucks on eBay. Remember about power supply though. In case of 2,5" disks you need +5V 1A power supply solely for HDD (current (Ampere) ratings depends on the disk, check on its cover). These power supplies may or m...

DVB-T tuner loses lock when starting omxplayer

Re: Sound

Not sure about apps using native system audio, but when using omxplayer (to play movies or music) you need to specify an extra option:

Code: Select all

omxplayer -o hdmi movie.mp4
Please let me know if it works.
