I have issues making my HVR work but thats not the point here. My problem is that since I updated kernel + drivers, I cant manage to make sound work when Im using the tuner input. Sound jack input works when Im using SVideo or Composite Video, but not when Im using tuner. Here are the options Im using tuner : port2=0 saa7134: oss=1 disable_ir=1 saa7134-oss: rate=48000 the rate=48000 is only valid for external analog input and disables sound from tuner. Have a look at the saa7134-oss mixer under such conditions. You must use default rate of 32000 for dma sound from tuner. The saa7134-oss is also soon deprecated and replaced by saa7134-alsa. If you are considering using recent v4l-dvb mercurial stuff, which should be best for the HVR1300 and reporting bugs on saa7134-empress, you might still have your old saa7134-oss module around and some others like the old video_buf now loaded, since not deleted on upgrade. After make rmmod and rminstall with current v4l-dvb you should delete such remaining modules on older kernels too before make install. Cheers, Hermann hum I used to set rate to 48000 with my old 2005 july snapshot and it was working even with tuner ... but ok Ill try 32000 ive tried alsa and I had the same results, that is no sound with tuner but line in sound with composite and svideo do I need some special stuffs compiled in my kernel except from config_snd ? about old modules still loaded this cant be since I build my system from scratch each time i try a new kernel / driver into an ext2 file, which I put on a 32MB flash disk and boot on it ... so Im sure Im not using my old v4l snapshot, but the 2.6.22.19 v4l drivers Ill let you know if I can make it work Ah, you are in France! yeah! Try "modinfo saa7134". Due to unresolvable auto detection issues between different SECAM standards there was a secam= either DK, L or Lc option introduced. huhu... but my system has to work worldwide ... so a module option is not a good idea, because it does not only depends on the country, but also if my customer is using a signal modulator or not, ... and I have two cards in my system, and I want to be able to select a certain SECAM mode with the first one, and another mode with the second card Actually Im selecting secam L, DK or BG with an ioctl cause my card can handle them (tested and working with older drivers/kernels) Anything else then 32000Hz sampling rate for TV is wrong currently and you get that input disabled on saa7134-oss mixer. Yes, it was once possible, but not intended, to use 48000 also for TV/Video on saa7134 chips, but gave very poor and crackling sound and is wrong. The current saa7134-alsa is simpler to use and also uses an exported mute symbol from saa7134-tvaudio. Default distribution settings are sufficient. On recent Ubutu releases seem to be problems with an out of tree alsa there. Ok Ill see with this rate thing and let you know Cheers, Hermann Greetings. I still have nothing with oss and rate=32000, with alsa, or with secam=l Anyway, some more informations : * Ive got the following error messages on saa7134 module insertion saa7134_empress: Unknown symbol saa7134_devlist saa7134_empress: Unknown symbol saa7134_common_ioctl saa7134_empress: Unknown symbol saa7134_boards saa7134_empress: Unknown symbol saa7134_ts_register saa7134_empress: Unknown symbol saa7134_ts_qops saa7134_empress: Unknown symbol saa7134_i2c_call_clients saa7134_empress: Unknown symbol saa7134_ts_unregister saa7134_alsa: Unknown symbol saa7134_tvaudio_setmute saa7134_alsa: Unknown symbol saa_dsp_writel saa7134_alsa: Unknown symbol saa7134_devlist saa7134_alsa: Unknown symbol saa7134_pgtable_alloc saa7134_alsa: Unknown symbol saa7134_pgtable_build saa7134_alsa: Unknown symbol saa7134_pgtable_free saa7134_alsa: Unknown symbol saa7134_dmasound_init saa7134_alsa: Unknown symbol saa7134_dmasound_exit saa7134_alsa: Unknown symbol saa7134_set_dmabits saa7134 ALSA driver for DMA sound loaded saa7134[0]/alsa: saa7134[0] at 0xe5300000 irq 5 registered as card -1 saa7134[1]/alsa: saa7134[1] at 0xe5301000 irq 9 registered as card -1 * When using audio_debug=1 for saa7134, Ive got the following : saa7134[1]/audio: mute/input: nothing to do [mute=1,input=Television] saa7134[1]/audio: sound IF not in use, skipping scan saa7134[1]/audio: mute/input: nothing to do [mute=1,input=Television] saa7134[1]/audio: mute/input: nothing to do [mute=1,input=Television] saa7134[1]/audio: ctl_mute=0 automute=0 input=Television = mute=0 input=Television saa7134[1]/audio: sound IF not in use, skipping scan saa7134[1]/audio: mute/input: nothing to do [mute=0,input=Television] saa7134[1]/audio: sound IF not in use, skipping scan saa7134[1]/audio: mute/input: nothing to do [mute=0,input=Television] saa7134[1]/audio: ctl_mute=0 automute=1 input=Television = mute=1 input=Television saa7134[1]/audio: sound IF not in use, skipping scan saa7134[1]/audio: ctl_mute=0 automute=0 input=Television = mute=0 input=Television Did I mention Im using 2.6.22.19 ? Hi, yes, that is the annoying part ;), but still fine, since others have been already restless on getting support with latest drivers on a 2.4.18 ! without to provide a single line of code themselves ... This is completely different with you, but we have other issues too. rel="nofollow" linuxtv.org/hg/v4l-dvb/rev/d6660f8c6dbb linuxtv.org/hg/v4l-dvb/rev/d6660f8c6dbb You might try to clean your /media modules and try with that snapshot. Not compile tested for 2.6.22, but might fit. Click on bz2 or gz on top. ok, Ill have a look at this asap Of course, if not auto detected you can select each TV analog standard separately for each card you have, but selectable SECAM was new. Do you have any progress on it or are you seriously asking me to look at a 2.6.22.19? My concern is to use any kernel while having full support for my knc tv station dvr AND my Hauppauge HVR 1300 ... that is, sound and mpeg compression I was using a 2.6.16.29 til now, with an old v4l (not v4l-dvb) snapshot so ... if I can still use my 2.6.16.29 and have support for my knc and my hauppauge within the same system, Ill be the happiest man (changing kernel is not an idea we like since by doing that well need time to test uptime equipments before releasing a new version of our products, ...) 2.6.22.19 is not mandatory but I know some things changed between 2.6.16 and recent kernels regarding modules (synopsis of some functions changed, ...) so adapting a recent snapshot against 2.6.16 might be painful ... You might remember, Im interested at the point, the encoder gave up. huhu, I know that Ill build 2.6.16 to 2.6.21 kernels this morning to see if my knc have sound in any of them with the modules included in the kernels (i.e I wont use my 2005 v4l snapshot) and let you know I cant get sound when selecting tuner with drivers included in kernel 2.6.16.29 ... whether I use alsa or oss options used : tda9887: port2=0 saa7134-oss : rate=32000 or rate=48000 (same results) saa7134: disable_ir=1 oss=1 or tda9887: port2=0 saa7134: disable_ir=1 alsa=1 I tried without port2=0, same results ... what do you mean by "the encoder gave up" ? Cheers, Hermann Regards
tests results :
* 2.6.12.6
sound working with tuner, saa7134 options are oss=1 oss_rate=48000 (32000 works too)
* 2.6.13.5Unable to handle kernel paging request at virtual address ...Modules linked in: saa7134_empress saa7134 ...
ok !!!!
* 2.6.14.7------------[ cut here ]------------kernel BUG at <bad filename :57323!invalid operand: 0000 [#1]Modules linked in: saa7134_empress saa7134 ....[...]Code: 07 83 c4 08 c3 8d 76 00 8b 42 08 40 78 1d b8 ff ff ff ff 89 44 24 04 c7 04 24 10 00 00 00 e8 15 07 ff ff 83 c4 08 c3 0f 0b eb cb <0f 0b eb df 89 f6 8d bc 27 00 00 00 00 83 ec 20 89 74 24 14 8b <1 Fixing recursive fault but reboot is needed!
huhum !!!
* 2.6.15.7
does not crach, but no sound when using tuner, whether I use rate=32000 or rate=48000 ... oss part has been moved to a new module : saa7134-oss ...
