Sound problem
On Dapper Drake (Ubuntu 6.06/june 2006), I lost the sound (PAL in Belgium) after a kernel upgrade in 2008. Last 'good' kernel was '2.6.15-51-386' (first quarter 2008). I used to keep the old 'good' kernel, but now, I switched to Karmic Koala (Ubuntu 9.10/october 2009) with a 2.6.31-16-generic kernel and I am unable to get the sound back (either by the board connector or through Linux)... How can I 'diff' related files (bttv.c, tvaudio.c,...)? Thanks. I just needed to specify 'options for tvaudio after 2.6.15-52-386; then it is fine to 2.6.15-55-386) -- Xof 17:21, 25 December 2009 (UTC)/ corrected : Xof 18:44, 16 January 2010 (UTC)
- It is possible to test if from a Dapper Live-cd (In Belgium/Voo/Liege):
- create the /etc/modprobe.d/bttv file (something like
alias char-major-89 i2c-dev options bttv card=100 tuner=38 bttv_debug=1 options tvaudio tda9874a=1 tda9874a_STD=8 tda9874a_AMSEL=1 tda9874a_SIF=2 debug=1 options tda9887 port1=0 port2=0 pal=1
- create a valid ~/.xawtv (something like:
[global] ratio = 4:3 freqtab = europe-west pixsize = 128 x 96 pixcols = 1 jpeg-quality = 85 keypad-ntsc = no keypad-partial = yes osd = yes osd-position = 30 , 20 use-wm-fullscreen = yes # [Station name] # capture = overlay | grabdisplay | on | off # input = Television | Composite1 | S-Video | ... # norm = PAL | NTSC | SECAM | ... # channel = # # fine = # (-128..+127) # key = keysym | modifier+keysym # color = # # bright = # # hue = # # contrast = # [defaults] group = main norm = PAL input = Television capture = grab color = 44% bright = 45% hue = 45% contrast = 40% [RTBf-1] channel = E8 [RTBf-2] channel = E9 [TF1] channel = E7 [A2] channel = E11
- get xawtv from universe
- sudo rmmod bt878
- sudo rmmod bttv
- sudo modprobe bttv
- sudo modprobe bt878
- xawtv
- and it is working. Rebooting on Karmic (no power-off!), the sound is still there but noisy and the mute/unmute control doesn't work. I saved the /var/log/* with modules' debug enabled; I'll check tomorrow. -- Xof 18:05, 2 January 2010 (UTC)
