Re: saa7134 problems and their solution?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



1) I had problems with video turning green after 1 hour,
but later I tried on another machine and video worked
perfectly. I did not try the original machine with
a different slot or other reconfigurations.

2) I have never had problem with the audio, and
I use sound both directly off the card DMA (use
aumix on a mixer device to set record on the
video channel and then grab off of that dsp.
I never figured out how to do this automatically,
but it comes up at boottime on the video line
full volume/recording enabled).

3) Both internal DMA (/dev/dsp1) and soundcard
(TV audio out to /dev/dsp0) work, though only 1
channel.  I use
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
options saa7134 video_nr=1 ts_nr=1 vbi_nr=1 radio_nr=1 card=2 mixer_nr=3 gbuffers=32 dsp_nr=1
pre-install saa7134 modprobe -k tuner;modprobe -k tda9887

(probably that tuner bit is wrong/unused)

If I changed from line1 or line2 to video,
I need to change the channel with v4lctl or xawtv
to get the sound to start coming out. Normally
there's no reason to change.

4) There is some conflict between the saa7134-0.10
code and the latest bttv code - I had to use an
earlier version of bttv to support my 2 cards at
the same time. Otherwise, lockups and other weirdness.
