Hi List, I have 3 soundcards on my laptop, which the USB-Audio is the one that I use for audio: cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xda100000 irq 49 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xda010000 irq 50 2 [CODEC ]: USB-Audio - USB Audio CODEC Burr-Brown from TI USB Audio CODEC at usb-0000:00:1a.1-1, full speed The other ones (Intel at IRQ49 and HDMI at IRQ50) are both named as "hda_intel" in /proc/interrupts cat /proc/interrupts CPU0 CPU1 0: 2154514 2010267 IO-APIC-edge timer 1: 5855 3 IO-APIC-edge i8042 8: 0 1 IO-APIC-edge rtc0 9: 3021 126 IO-APIC-fasteoi acpi 12: 79 168302 IO-APIC-edge i8042 16: 251 150500 IO-APIC-fasteoi uhci_hcd:usb3, uhci_hcd:usb7, jmb38x_ms:slot0, mmc0, eth1 18: 0 0 IO-APIC-fasteoi uhci_hcd:usb8 19: 0 3 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb6 20: 16 14 IO-APIC-fasteoi ehci_hcd:usb2, uhci_hcd:usb5 21: 5123 1 IO-APIC-fasteoi uhci_hcd:usb4 46: 0 0 PCI-MSI-edge eth0 47: 50155 2690 PCI-MSI-edge ahci 48: 188 4372 PCI-MSI-edge radeon 49: 332 226 PCI-MSI-edge hda_intel 50: 138 252 PCI-MSI-edge hda_intel NMI: 0 0 Non-maskable interrupts LOC: 1223006 1601379 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 0 0 Performance monitoring interrupts IWI: 0 0 IRQ work interrupts RES: 16171 8941 Rescheduling interrupts CAL: 5353 4038 Function call interrupts TLB: 2520 2658 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 18 18 Machine check polls So my question is: How to name the service name in the RTIRQ_NAME_LIST in rtirq.conf if both cards are named as "hda_intel"? I think that a solution will be to blacklist the HDA ATI HDMI, but I would like to know if there is some other way. Thank you very much. Diego
