I have the hardware - both ES1968 (SF64-PCE2-04) and FM801 cards (SF64-PCR) with these tuners. I remember fixing mute in tea5757x-tuner back in 2009 (testing it on SF64-PCR). > I don't like the idea to duplicate code. I don't like that either. I've done a quick hack - copied radio support from fm801 and radio_bits_get() and radio_bits_set() from radio-maestro to es1968 and it seems to basically work. Now I just need some more time to finish it, then move everything good from radio-maestro to tea575x-tuner and delete radio-maestro. IIRC, the TEA5757 tuner is also present on at least one ISA radio card - SF16-FMR2 (which I also have). -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

My concern is that having both testers might be not easy, if we need to change something in tea575-tuner side. (We have already the same code, so porting it doesn't increase the code size :) Anyway I agree to unify in a long term. Let's see whether tea-575x works as is. thanks, Takashi > I don't like the idea to duplicate code. > > Regards, > > Hans > > > If we have active testers for both devices, it's nicer to go forward > > to clean-up works indeed, though. > > > > > > thanks, > > > > Takashi > > > >> Both are for the tea575x tuner, although radio-maestro seems to have > >> better > >> support for the g_tuner operation.

I assume someone has hardware since someone reported this breakage. So try to use tuner-tea575x for the es1968. It shouldn't be too difficult. Additional cleanup should probably wait until we find a tester for the fm801 as well. I don't like the idea to duplicate code.

I guess simply porting radio-maestro codes into snd-es1968 would work without much hustles, and it's a bit safe way to go for now; smaller changes have less chance for breakage, and as little people seem using this driver, it'd be better to take a safer option, IMO. If we have active testers for both devices, it's nicer to go forward to clean-up works indeed, though. thanks, Takashi > Both are for the tea575x tuner, although radio-maestro seems to have better > support for the g_tuner operation.
