If you installed from the v4l-dvb repository, then 'modinfo bttv' should
show the audiodev module option. It does for me. I'm not sure how you can
get a bttv version of 0.9.18 without seeing that module option. I'm
assuming your v4l-dvb tree is up to date?

Hi,
you can see at my dmesg output
[ 2282.430209] bttv: driver version 0.9.18 loaded

i have done
hg clone http://linuxtv.org/hg/v4l-dvb
cd v4l-dvb
make && make install 
reboot
No idea why I don't have the audiodev modparam?

Halim, we should get that in sync.

parm:           autoload:obsolete option, please do not use anymore (int)
parm:           audiodev:specify audio device:
                -1 = no audio
                 0 = autodetect (default)
                 1 = msp3400
                 2 = tda7432
                 3 = tvaudio (array of int)
parm:           saa6588:if 1, then load the saa6588 RDS module, default (0) is to use the card definition.
parm:           no_overlay:allow override overlay default (0 disables, 1 enables) [some VIA/SIS chipsets are known to have problem with overlay] (int)

Hopefully we don't need to fall back on Konfuzius for it ;)

Cheers,
Hermann

Hi,
Ok I have tested 
modprobe bttv audiodev=-1 card=34 tuner=24 gbuffers=16

I am seeing again the delay.
More ideas?

Use more printk messages in the bttv_init_card2() function to try and narrow 
down the exact function call that is causing the delay. I still have no 
idea what it might be.

Hi Halim,

Did you have time to try and narrow this down?

I couldn't find a parameter audiodev in bttv module
Do you mean audioall??
It has no effect.
So I need an older revision of v4l-dvb to test the 17. drivers.
Thanks

When you tested this with bttv 0.9.17, wasn't the delay then before the
text 'tuner type=24'?

Anyway, if you modprobe with the option 'audiodev=-1', will that solve
this? If not, then can you do the same printk trick in the bttv_init_card2
function?

Hi,
sorry for the nusable output!
I found the time consuming funktion:
        bttv_init_card2(btv);
This takes about 4 min. today.
my new testcode:
        /* needs to be done before i2c is registered */
printk("linke 2:bttv_init_card1(btv);\n");

        bttv_init_card1(btv);

        /* register i2c + gpio */
printk("line 3: init_bttv_i2c(btv);\n");

        init_bttv_i2c(btv);

        /* some card-specific stuff (needs working i2c) */
printk("line4:         some card-specific stuff needs working i2c \n");
        bttv_init_card2(btv);
printk("irq init\n");

        init_irqreg(btv);
