JS1INT JS0ST JS1ST JS0MD JS1MD JS0TMR JS1TMR JS0EQB JS1EQB JSMT [2:0] JS0INT This bit indicates that Pin JS0 has generated an interrupt. This bit remains set until the software services the JS0 interrupt, that is, JS0 ISR should clear this bit by writing a 0 to it. The interrupt to the system is an OR combination of this bit and JS1INT. The actual interrupt implementation is selected by the INTS bit (Register 0x76). It is also possible to generate a software system interrupt by writing a 1 to this bit. Js1 Interrupt This bit indicates that Pin JS1 has generated an interrupt. This bit remains set until the software services the JS1 interrupt, that is, JS1 ISR should clear this bit by writing a 0 to it. See the JS0INT description for details. JS0 State This bit always reports the logic state of the JS0 pin. JS1 State This bit always reports the logic state of the JS1 pin. JS0 Mode This bit selects the operation mode for the JS0 pin. 0 = Jack sense mode (default). 1 = Interrupt mode. JS1 Mode This bit selects the operation mode for the JS1 pin. 0 = Jack sense mode (default). 1 = Interrupt mode. JS0 Timer Enable If this bit is set to 1, JS0 must be high for >278 ms to be recognized. JS1 Timer Enable If this bit is set to 1, JS1 must be high for >278 ms to be recognized. JS0 EQ Bypass Enable This bit enables JS0 to control the EQ bypass. When this bit is set to 1, JS0 = 1 causes the EQ to be bypassed. JS1 EQ Bypass Enable This bit enables JS1 to control the EQ bypass. When this bit is set to 1, JS1 = 1 causes the EQ to be bypassed. JS Mute Enable Selector These three bits select and enable the jack sense muting action (see Table 41 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/893210 Title: [Dell OptiPlex GX620 - AD1981b, playback] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/alsa-driver/+bug/893210/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
