For therecord, using tuner type 50, the tuner audio for analog captures worksfor me with the latest v4l-dvb.

Hans' made a fix to make the firmware load more robustand things started working. If your tuner looks like it's gettingcommanded properly, we'll investigate microcontroller firmware loadnext. > > Does a TCL M2523_5N_E have a TDA988x? I know the TDA9887 can> > demodulate FM radio.

From the link you gave: ·IC type: SN761678 & TDA9801T So a TDA9801 is the demodulator-PLL chip on this TCL tuner.

My PVR-150MCE has an LG TAPE H001F (type 47). The tape is a rebrandedPhillips FM1236 MK3 (type 43) and it does have a tda988x. I figured outa few years ago how to get the FM radio working right for the TAPEH001F, and Hans' helped me figure that the TAPE H001F was a clone of theFM1236 MK3. > Then exactly the above missing .has_tda9887 = 1 for _that one_ could> cause such problems.> > It just came in mind it might be related to the missing tda9887 for> tuner=57, but you obviously deal with other tuners.

For the FQ1236A MK4 It looks inconsistent to me too. You're probablyright. I don't have a PVR card with that tuner to test though, and Ican't find a datasheet for the FQ1236A MK4 to verify your observation.
