Hello, I have a old AverTV Hybrid NanoExpress card sold several years ago by DELL that runs well on Windows, but I would like to make it working on Linux. There were several models of this card as described in https://linuxtv.org/wiki/index.php/AVerMedia_AVerTV_Hybrid_NanoExpress. Apart from the Avermedia models there are others sold by Dell that they labelled as HC82 (DVB) and HC82 (ASTC). Mine is HC82 (DVB). Dell has a Diagnostic tool that give this information: [21:59:19] === Device Information === [21:59:19] Capture filter friendlyname:AVerMedia 716x BDA Analog Capture [21:59:19] Model Name: AVerMedia HC82 (Hybrid DVBT) [21:59:19] Transmission Interface: PCI Express [21:59:19] Supported Standards: NTSC/PAL/SECAM/DVB-T [21:59:19] TV Tuner: TDA18271 [21:59:19] Audio/Video Decoder: SAA7136 [21:59:19] Encoder: N/A [21:59:19] Ditial TV Demodulator: ZL10353 [21:59:19] === Driver Version === [21:59:19] Bridge: Error!

In order to try to install a driver for linux I followed the instructions given in https://www.vdr-portal.de/forum/index.php?thread/134377-tt-s2-6400-saa716x-kompilieren-unter-20-04/ to patch the linux sources: #!/bin/sh # # Build modules under Ubuntu-20.04 LTS for TechnoTrend DVB S2-6400 # Based on https://www.vdr-portal.de/forum/index.php?thread/132415-tt-s2-6400-saa716x-kompilieren-unter-18-04/&postID=1337903#post1337903 # URL=https://github.com/s-moch/linux-saa716x/compare BUILDDIR=~/linux-saa716x LOGFILE=$BUILDDIR/linux-saa716x.log KERNELVERSION=$(uname -r) KMAJOR=$(uname -r | cut -d'.' -f1) KMINOR=$(uname -r | cut -d'.' -f2) KSOURCE=$(uname -r | cut -d'-' -f1) DIFF=saa716x-$KMAJOR.$KMINOR.diff sudo apt install fakeroot build-essential devscripts libncurses5 libncurses5-dev bison flex libssl-dev pv wget linux-source-$KSOURCE linux-headers-$KERNELVERSION rm -rf $BUILDDIR mkdir -p $BUILDDIR cd $BUILDDIR wget $URL/$DIFF echo "Kernel Sources entpacken..." pv /usr/src/linux-source-$KSOURCE.tar.bz2 | bzip2 -d | tar x cd linux-source-$KSOURCE cp /boot/config-$KERNELVERSION .config cp /usr/src/linux-headers-$KERNELVERSION/Module.symvers . printf "#\n# Kernelversion: $KERNELVERSION\n#\n" >$LOGFILE patch -p1 < ../$DIFF | tee -a $LOGFILE printf "y\nm\nm\nm\nm\n" | make oldconfig | tee -a $LOGFILE make KERNELVERSION=$KERNELVERSION -j6 modules_prepare | tee -a $LOGFILE make KERNELVERSION=$KERNELVERSION -j6 M=drivers/media/pci/saa716x/ modules | tee -a $LOGFILE sudo cp drivers/media/pci/saa716x/saa716x_core.ko /lib/modules/$KERNELVERSION/kernel/drivers/media/pci/ sudo cp drivers/media/pci/saa716x/saa716x_ff.ko /lib/modules/$KERNELVERSION/kernel/drivers/media/pci/ sudo depmod $KERNELVERSION adding a line to copy saa716x_hybrid.ko module when created. I modified the saa716x_hybrid.h and saa716x_hybrid.c to adapt them to AverTV Hybrid NanoExpress HC82 card (I deleted the code for the others cards, sorry): saa716x_hybrid.h #ifndef __SAA716x_HYBRID_H #define __SAA716x_HYBRID_H #define AVERMEDIA 0x1461 #define AVERMEDIA_HC82 0x0555 #endif /* __SAA716x_HYBRID_H */ and saa716x_hybrid.c /* * Avermedia Hybrid NanoExpress DVB-T * * DVB-T Test */ #define SAA716x_MODEL_AVERMEDIA_HC82 "AVERMEDIA NanoExpress Hybrid" #define SAA716x_DEV_AVERMEDIA_HC82 "DVB-T + Analog" //#if 0 // These data are from a old version of the driver by Manu Abraham, but I'm not sure this parameters correspond to this model. static struct zl10353_config saa716x_hc82_zl10353_config = { .demod_address = 0x1f , .adc_clock = 450560, .if2 = 361667, .no_tuner = 1, .parallel_ts = 1, }; //#endif static int saa716x_hc82_frontend_attach(struct saa716x_adapter *adapter, int count) { struct saa716x_dev *saa716x = adapter->saa716x; struct saa716x_i2c *demod_i2c = &saa716x->i2c[SAA716x_I2C_BUS_B]; pci_dbg(saa716x->pdev, "Adapter (%d) Power ON", count); pci_dbg(saa716x->pdev, "Adapter (%d) SAA716x frontend Init", count); pci_dbg(saa716x->pdev, "Adapter (%d) Device ID=%02x", count, saa716x->pdev->subsystem_device); adapter->fe = zl10353_attach(&saa716x_hc82_zl10353_config,&demod_i2c->i2c_adapter); return 0; } The script executes without errors and the module saa716x_hybrid.ko is generated. When loaded with sudo modprobe saa716x_hybrid the output of dmesg is: [ 3978.615919] SAA716x Hybrid 0000:0d:00.0: found a AVERMEDIA NanoExpress Hybrid PCIe card [ 3978.616140] SAA716x Hybrid 0000:0d:00.0: SAA7160 Rev 3, irq: 25 (MSI) [ 3978.661590] dvbdev: DVB: registering new adapter (SAA716x dvb adapter) [ 3978.765613] SAA716x Hybrid 0000:0d:00.0: I2C transfer error, msg 0, addr = 0x1f, len=1, flags=0x0 [ 3978.765628] zl10353_read_register: readreg error (reg=127, ret==-5) [ 3978.765636] SAA716x Hybrid 0000:0d:00.0: A frontend driver was not found for [1131:7160] subsystem [1461:0555] So, the card is detected but the frontend is not loaded. In fact, the dvb device is created and also you could found the next devices: /dev/dvb/adapter0 /dev/dvb/adapter0/demux0 /dev/dvb/adapter0/dvr0 /dev/dvb/adapter0/net0 Perhaps I need more information about the card but I have no idea what to do next. Any suggestions would be appreciated. Thanks. José Manuel Sorry if I have send this mail to the owner of the list too.
