Hi Karl. For what it's worth, I have a PVR500 and I have been fighting this problem for over 18 months.
I keep reading that cards with the Samsung tuners have all kinds of problems, but I am fortunate enough to have the Phillips tuners in mine. Despite, that, I keep encountering the issue. I tried the 0.10.x drivers, but I was unable to get them working properly with 2.6.22r5 (I was only able to get unintelligible static with that combination). In the end, I had the best luck with: 1) kernel = 2.6.16r13 (gentoo) 2) ivtv = 0.6.7 That said, I still get the static from time to time. I've had a bunch of theories about what brings it on (PVR500 overheating, unamplified cable signal, old kernel, old drivers, etc.) but I have yet to find the answer. I have noticed that, for me, this problem seems to occur more frequently on the lower channels (US-cable 7-10) vs. higher ones. Still, I have seen this on the higher channels now and then. One thing we have in common is that a PVR500 (my card) is essentially two PVR150s (your cards). Also worth mentioning is my other hardware: 1) CPU = AMD Sempron (AMD64) @ 1GHz 2) RAM = 1GB 3) Chipset = nVidia nForce (disabled onboard GPU = nVidia 6100) 4) Active Video Card = nVidia 6200 (64MB, PCI Express 16x) And here's the obligatory dmesg output: Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.6.7 (tagged release) loading ivtv: Linux version: 2.6.16-gentoo-r13 SMP gcc-3.4 ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist. ivtv0: Autodetected Hauppauge WinTV PVR-150 card (cx23416 based) ACPI: PCI Interrupt Link [APC1] enabled at IRQ 16 GSI 20 sharing vector 0x32 and IRQ 20 ACPI: PCI Interrupt 0000:05:08.0[A] -> Link [APC1] -> GSI 16 (level, low) -> IRQ 50 ivtv0: Unreasonably low latency timer, setting to 64 (was 32) tveeprom 0-0050: Hauppauge model 23552, rev E587, serial# 8382698 tveeprom 0-0050: tuner model is Samsung TCPN 2121P30A (idx 87, type 70) tveeprom 0-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 0-0050: second tuner model is Philips TEA5768HL FM Radio (idx 101, type 62) tveeprom 0-0050: audio processor is CX25843 (idx 37) tveeprom 0-0050: decoder processor is CX25843 (idx 30) tveeprom 0-0050: has radio, has no IR remote ivtv0: This is the first unit of a PVR500 tuner 0-0060: TEA5767 detected. tuner 0-0060: chip found @ 0xc0 (ivtv i2c driver #0) tuner 0-0060: type set to 62 (Philips TEA5767HN FM Radio) tuner 0-0061: chip found @ 0xc2 (ivtv i2c driver #0) cx25840 0-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #0) cx25840 0-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 0-001b: chip found @ 0x36 (ivtv i2c driver #0) ivtv0: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv0: Encoder revision: 0x02060039 ivtv0: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv0: Allocate DMA encoder YUV stream: 194 x 10800 buffers (2048KB total) ivtv0: Allocate DMA encoder VBI stream: 120 x 17472 buffers (2048KB total) ivtv0: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) ivtv0: Create encoder radio stream tuner 0-0061: type set to 70 (Samsung TCPN 2121P30A) ivtv0: Initialized WinTV PVR 500 (unit #1), card #0 ivtv: ====================== NEXT CARD ====================== ivtv1: Autodetected Hauppauge WinTV PVR-150 card (cx23416 based) ACPI: PCI Interrupt Link [APC2] enabled at IRQ 17 GSI 21 sharing vector 0x3A and IRQ 21 ACPI: PCI Interrupt 0000:05:09.0[A] -> Link [APC2] -> GSI 17 (level, low) -> IRQ 58 ivtv1: Unreasonably low latency timer, setting to 64 (was 32) tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #1) cx25840 1-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #1) cx25840 1-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 1-001b: chip found @ 0x36 (ivtv i2c driver #1) tveeprom 1-0050: Hauppauge model 23552, rev E587, serial# 8382698 tveeprom 1-0050: tuner model is Samsung TCPN 2121P30A (idx 87, type 70) tveeprom 1-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 1-0050: second tuner model is Philips TEA5768HL FM Radio (idx 101, type 62) tveeprom 1-0050: audio processor is CX25843 (idx 37) tveeprom 1-0050: decoder processor is CX25843 (idx 30) tveeprom 1-0050: has radio, has no IR remote ivtv1: This is the second unit of a PVR500 ivtv1: Correcting tveeprom data: no radio present on second unit ivtv1: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv1: Encoder revision: 0x02060039 ivtv1: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv1: Allocate DMA encoder YUV stream: 194 x 10800 buffers (2048KB total) ivtv1: Allocate DMA encoder VBI stream: 120 x 17472 buffers (2048KB total) ivtv1: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) tuner 1-0061: type set to 70 (Samsung TCPN 2121P30A) ivtv1: Initialized WinTV PVR 500 (unit #2), card #1 ivtv: ==================== END INIT IVTV ==================== On Feb 3, 2008, at 6:00 AM, [EMAIL PROTECTED] wrote: > Message: 3 > Date: Sat, 02 Feb 2008 16:00:53 -0500 > From: Karl Grindley <[EMAIL PROTECTED]> > Subject: [ivtv-users] Tinny audio on 0.10.6 with pvr150s > To: User discussion about IVTV <[email protected]> > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; charset=ISO-8859-1 > > > Greetings, > > I've got two pvr150s and a pvr350 all running on 2.6.18 with 0.10.6. > Tinny audio occasionally occurs with about 20% of recordings.
