Summary 07968: All machines in hornet.cpp: Sound devices fail self test
Description With the "Skip Post" dip set to off (default is on), the self test for the sound devices fails (see attached snap taken with the gradius4 set).
Steps To Reproduce Load game
Set the "Skip Post" dip to off
Reset
Wait for the self test to get to the sound devices
Additional Information This are the tested devices, thanks to Guru for cross-checking on a real PCB:

5P = 68000
7S = EPROM.7S
14H/16H = 2x 32kx8 SRAMs
12K = RF5C400

Couldn't find any obvious cause by skimming the 0.228 diff.

Not a fix, but might point in the right direction: commenting out m_audiocpu->set_input_line(INPUT_LINE_RESET, (data & 0x80) ? CLEAR_LINE : ASSERT_LINE); in the sysreg_w(offs_t offset, uint8_t data) method makes the sets pass the test.

Happens with all nwk-tr sets too since they run on very similar hardware and go through a similar post sequence.

Huh, no. Nwk-tr.cpp sets don't fail the sound devices test, as the audiocpu reset line isn't hooked up in that driver.
They fail the lan board tests, but It has happened for a long time if not from when the driver was added (went back to 0.160)
