My machine can sleep but not hibernate. After sleep the sound is
resumed well.
I also edited cs4231_lib.c and changed lines 242 and 861 from "#if 0"
to "#if 1" (thus enabling the call to snd_cs4231_debug(chip) at the
end of snd_cs4231_playback_prepare() ). Here is the output I got:
1. module opl3sa2
a. First time running aplay:
CS4231 REGS: INDEX = 0x0e STATUS = 0xc4
0x00: left input = 0x00 0x10: alt 1 (CFIG 2) = 0x80
0x01: right input = 0x00 0x11: alt 2 (CFIG 3) = 0x01
0x02: GF1 left input = 0x06 0x12: left line in = 0x9f
0x03: GF1 right input = 0x06 0x13: right line in = 0x9f
0x04: CD left input = 0x9f 0x14: timer low = 0x00
0x05: CD right input = 0x9f 0x15: timer high = 0x00
0x06: left output = 0x0c 0x16: left MIC (PnP) = 0x80
0x07: right output = 0x0c 0x17: right MIC (PnP) = 0x80
0x08: playback format = 0x57 0x18: IRQ status = 0x00
0x09: iface (CFIG 1) = 0x08 0x19: left line out = 0x80
0x0a: pin control = 0x02 0x1a: mono control = 0x0f
0x0b: init & status = 0x20 0x1b: right line out = 0x80
0x0c: revision & mode = 0xca 0x1c: record format = 0x20
0x0d: loopback = 0xfc 0x1d: var freq (PnP) = 0x80
0x0e: ply upr count = 0x0a 0x1e: ply lwr count = 0x00
0x0f: rec upr count = 0xc3 0x1f: rec lwr count = 0x00
b. Second time running aplay:
CS4231 REGS: INDEX = 0x0e STATUS = 0xc4
0x00: left input = 0x00 0x10: alt 1 (CFIG 2) = 0x80
0x01: right input = 0x00 0x11: alt 2 (CFIG 3) = 0x01
0x02: GF1 left input = 0x06 0x12: left line in = 0x9f
0x03: GF1 right input = 0x06 0x13: right line in = 0x9f
0x04: CD left input = 0x9f 0x14: timer low = 0x00
0x05: CD right input = 0x9f 0x15: timer high = 0x00
0x06: left output = 0x0c 0x16: left MIC (PnP) = 0x80
0x07: right output = 0x0c 0x17: right MIC (PnP) = 0x80
0x08: playback format = 0x57 0x18: IRQ status = 0x00
0x09: iface (CFIG 1) = 0x08 0x19: left line out = 0x80
0x0a: pin control = 0x02 0x1a: mono control = 0x0f
0x0b: init & status = 0x00 0x1b: right line out = 0x80
0x0c: revision & mode = 0xca 0x1c: record format = 0x20
0x0d: loopback = 0xfc 0x1d: var freq (PnP) = 0x80
0x0e: ply upr count = 0x0a 0x1e: ply lwr count = 0x00
0x0f: rec upr count = 0xc3 0x1f: rec lwr count = 0x00
2. Module cs4232, both times running aplay:
CS4231 REGS: INDEX = 0x0e STATUS = 0xc4
0x00: left input = 0x00 0x10: alt 1 (CFIG 2) = 0x80
0x01: right input = 0x00 0x11: alt 2 (CFIG 3) = 0x01
0x02: GF1 left input = 0x9f 0x12: left line in = 0x9f
0x03: GF1 right input = 0x9f 0x13: right line in = 0x9f
0x04: CD left input = 0x9f 0x14: timer low = 0x00
0x05: CD right input = 0x9f 0x15: timer high = 0x00
0x06: left output = 0x0c 0x16: left MIC (PnP) = 0x80
0x07: right output = 0x0c 0x17: right MIC (PnP) = 0x80
0x08: playback format = 0x57 0x18: IRQ status = 0x00
0x09: iface (CFIG 1) = 0x08 0x19: left line out = 0x80
0x0a: pin control = 0x02 0x1a: mono control = 0xcf
0x0b: init & status = 0x00 0x1b: right line out = 0x80
0x0c: revision & mode = 0xca 0x1c: record format = 0x20
0x0d: loopback = 0xfc 0x1d: var freq (PnP) = 0x80
0x0e: ply upr count = 0x0a 0x1e: ply lwr count = 0x00
0x0f: rec upr count = 0xc3 0x1f: rec lwr count = 0x00
The value of 0x0b in the first group is different from the other two groups.
